<h3 id="_general">General</h3>
<div class="sect3">
<h4 id="_improved_interactive_performance_and_reduced_memory_consumption">Improved interactive performance and reduced memory consumption</h4>
<div class="paragraph"><p>This and earlier milestones contain a multitude of fixes to enhance interactive and startup performance of the Eclipse IDE, and to reduce overall memory consumption.</p></div>
<div class="paragraph"><p>TBD: insert some benchmarks</p></div>
</div>
<div class="sect3">
<h4 id="_import_projects">Import Projects</h4>
<div class="paragraph"><p>A new <strong>Import Projects</strong> wizard is available via the <span class="monospaced">File &gt; Open Projects...</span>
menu and via the general <span class="monospaced">Import...</span> command under <span class="monospaced">General &gt; Projects</span> from Folder
or Archive.</p></div>
<div class="paragraph"><p>Compared to other ways to import or create projects, this wizard aims at being
a universal wizard that, from a source directory or archive, can detect and
configure various kinds of projects.</p></div>
<div class="imageblock">
<div class="content">
<img src="images/import-projects.png" alt="images/import-projects.png">
</div>
</div>
<div class="paragraph"><p>This wizard relies on an extensible set of strategies that look at the content
of the import source to detect file types, project layout patterns, or even
look into some files in order to deduct which folders should be turned into
projects and how those should be configured. Configuration usually involves
setting up project natures and preferences.</p></div>
<div class="paragraph"><p>The import strategies are contributed via the new extension point
<span class="monospaced">org.eclipse.ui.ide.projectConfigurator</span>, so that other IDE components can contribute
detection and configuration specific to the technology they&#8217;re supporting.</p></div>
</div>
<div class="sect3">
<h4 id="_search_in_binary_files">Search in binary files</h4>
<div class="paragraph"><p>The <span class="monospaced">Search &gt; File&#8230;</span> dialog has a new option to search in binary files as well.</p></div>
<div class="imageblock">
<div class="content">
<img src="images/search-binary-files.png" alt="images/search-binary-files.png">
</div>
</div>

have the <strong>Text</strong> content type, or in files that have no content type and don&#8217;t
contain the null character (<span class="monospaced">\u0000</span>).</p></div>
</div>
<div class="sect3">
<h4 id="_automatic_save_of_dirty_editors">Automatic Save of dirty editors</h4>
<div class="paragraph"><p>Auto-save of dirty editors is now available in Eclipse. The autosave option is disabled by default. A new autosave preference page (Preferences &gt; General &gt; Editors &gt; Autosave) is available and allows to enable/disable the autosave and change the interval of autosave. The countdown is reset on keyboard activity, mouse click, or when a popup is displayed (e.g. content assist, preference page, &#8230;).</p></div>

<h3 id="_look_and_feel">Look and Feel</h3>
<div class="sect3">
<h4 id="_resolution_based_image_auto_scaling">Resolution-based image auto-scaling</h4>
<div class="paragraph"><p>Images now automatically scale on high-DPI monitors on Windows and Linux,
similar to the Mac&#8217;s Retina support on OS X. In the absence of high-resolution
images, available images are automatically scaled proportionately to the
resolution of the monitor.</p></div>

<h4 id="_preference_setting_to_disable_css_based_theming">Preference setting to disable CSS based theming</h4>
<div class="paragraph"><p>You can disable the CSS-based styling of the Eclipse IDE via
<span class="monospaced">Preferences &gt; General &gt; Appearance &gt; Enable theming</span>. This will prevent the Eclipse
Workbench from rendering custom colors, shades, and borders, and may result in better
performance.</p></div>

<h4 id="_full_screen">Full Screen</h4>
<div class="paragraph"><p>The Full Screen feature is now also available on Windows and Linux. You can toggle
the mode via shortcut (<span class="monospaced">Alt+F11</span>) or menu (<span class="monospaced">Window &gt; Appearance &gt; Toggle Full Screen</span>).</p></div>
<div class="paragraph"><p>When Full Screen is activated, you&#8217;ll see a dialog which tells you how to turn it off again.</p></div>
</div>
<div class="sect3">
<h4 id="_hide_the_window_toolbars">Hide the window toolbars</h4>
<div class="paragraph"><p>You can use the Toggle Visibility of all Toolbars command (via Quick Access:
<span class="monospaced">Ctrl+3</span> or <span class="monospaced">Command+3</span>) to hide all currently visible toolbars of the currently
window. Selecting the command again, reveals these toolbars again. This allows
the developer to maximize the space available for editors and views. If you
minimize a stack after you selected this command, the minimized stack will be
visible until you trigger the command to hide the toolbars again. This allows
you to decide which minimized stacks are currently useful for you.</p></div>
<div class="paragraph"><p>The following is a screenshot of the IDE with a maximized Java editor
and several toolbars visible.</p></div>

<div class="paragraph"><p>The interplay of <span class="monospaced">null</span> annotations and generics has been improved in several
regards.</p></div>
<div class="paragraph"><p>The basic concepts had already been documented in the online help, but not
all that was documented was actually checked by <span class="monospaced">null</span> analysis. With
the changes outlined below, null analysis based on type annotations is even
more capable than previous versions.</p></div>
<div class="paragraph"><p>(1) The first batch of contributed improvements implements what we call
<em>pessimistic analysis for free type variables</em>, which affects implementors
of generic types.</p></div>
<div class="imageblock">
<div class="content">
<img src="images/pessimistic-analysis.png" alt="images/pessimistic-analysis.png">
</div>
</div>
<div class="paragraph"><p>In order to allow clients to instantiate such a generic class with either
a <span class="monospaced">@NonNull</span> or a <span class="monospaced">@Nullable</span> type as substitution for the "free type variable"
<span class="monospaced">&lt;T&gt;</span>, the implementation of that class must account for the worst in both
directions:</p></div>
<div class="ulist"><ul>
<li>
<p>
To anticipate a <span class="monospaced">@NonNull</span> type, each field typed to a free type variable
must be initialized with a non-<span class="monospaced">null</span> value, and passing <span class="monospaced">null</span> where <span class="monospaced">T</span> is
expected is illegal; and
</p>
</li>
<li>
<p>
To anticipate a <span class="monospaced">@Nullable</span> type, each dereference must be preceded by a <span class="monospaced">null</span> check.
</p>
</li>
</ul></div>
<div class="paragraph"><p>At the bottom of each problem hover, you will find a link to the corresponding
configuration option, should you like to change the severity of this diagnostic.
Note that configurability is mainly given for smooth migration from previous
JDT version; conceptually, problems detected by pessimistic analysis should be
treated as errors, because they invalidate the null-guarantees given by a generic
type.</p></div>
<div class="imageblock">
<div class="content">
<img src="images/configure-pessimistic-analysis.png" alt="images/configure-pessimistic-analysis.png">
</div>
</div>
<div class="paragraph"><p>(2) The second improvement concerns consumption of generic types from a library,
more specifically: invocations of library methods whose return type is given by
a free type variable.</p></div>
<div class="paragraph"><p>If the library type is instantiated with a <span class="monospaced">@NonNull</span> type as the type argument,
we generally want to interpret the mentioned return type as non-<span class="monospaced">null</span>, too.
This is problematic only for some "legacy" methods, which may return <span class="monospaced">null</span>
without declaring so. The most prominent example is <span class="monospaced">java.util.Map.get(K)</span>.</p></div>
<div class="paragraph"><p>The analysis cannot see whether absence of a null annotation for such a return
type is intentional (in the above sense of "free type variables"), or an omission
that should be fixed. For that reason a new warning has been implemented to alert
about this situation.</p></div>
<div class="imageblock">
<div class="content">
<img src="images/unsafe-nonnull-interpretation.png" alt="images/unsafe-nonnull-interpretation.png">
</div>
</div>
<div class="paragraph"><p>In the above example, both fields list and map provide <span class="monospaced">@NonNull</span> <span class="monospaced">String</span> as a type
argument, hence the return types of both <em>get</em> methods are interpreted as non-<span class="monospaced">null</span>.
For <span class="monospaced">List</span> this is desired, for <span class="monospaced">Map</span> it is a bug.</p></div>
<div class="paragraph"><p>The dilemma can be resolved by adding a (possibly empty) external annotation file
(<span class="monospaced">.eea</span>) to each affected library class. By using an empty annotation file, the user
signals that all types in this class should be interpreted verbatim (like in the
<span class="monospaced">List</span> case - use with care). In the other case, the missing <span class="monospaced">@Nullable</span> annotation
should be added as an external annotation (like in the <span class="monospaced">Map</span> case).</p></div>
<div class="paragraph"><p>In a project that is not yet configured to use external annotations for the
library in question, the warning is demoted to level "information". Generally, the
severity of this problem is configured using the option right below the one mentioned
above, titled <span class="monospaced">Unsafe '@NonNull'</span> interpretation of free type variable from library.</p></div>
<div class="paragraph"><p>(3) Finally, a small utility class, <span class="monospaced">org.eclipse.jdt.annotation.Checks</span>, has been
included in the bundle <span class="monospaced">org.eclipse.jdt.annotation_2.1.0</span> containing helper methods
for typical idioms for improving and documenting <span class="monospaced">null</span> safety.</p></div>

<div class="paragraph"><p>When a "potential null pointer access" problem is raised against a local variable,
the reason is not always obvious. Perhaps <span class="monospaced">null</span> is assigned somewhere deep inside
a complex control flow. If annotation-based <span class="monospaced">null</span> analysis is enabled, a new
<em>Quick Fix</em> is offered (<span class="monospaced">Ctrl+1</span>), that adds a <span class="monospaced">@NonNull</span> annotation to the local
