+      name="mozTocId315234" />Target Operating Environments
+  </h2>
+  <p>In order to remain current, each Eclipse Project release targets reasonably current operating environments.</p>
+  <p>Most of the Eclipse SDK is "pure" Java code and has no direct dependence on the underlying operating system. The chief dependence is therefore on the Java Platform itself. Portions are
+    targeted to specific classes of operating environments, requiring their source code to only reference facilities available in particular class libraries (e.g. J2ME Foundation 1.1, J2SE 1.4, Java
+    5, etc).</p>
+  <p>In general, the 4.27 release of the Eclipse Project is developed on Java SE 11 VMs. As such, the Eclipse SDK as a whole is targeted at all modern, desktop Java VMs.</p>
+  <p>
+    <a href="#appendix">Appendix 1</a> contains a table that indicates the class library level required for each bundle.
+  </p>
+  <p>
+    There are many different implementations of the Java Platform running atop a variety of operating systems. We focus our testing on a handful of popular combinations of operating system and Java
+    Platform; these are our <em>reference platforms</em>. Eclipse undoubtedly runs fine in many operating environments beyond the reference platforms we test. However, since we do not systematically
+    test them we cannot vouch for them. Problems encountered when running Eclipse on a non-reference platform that cannot be recreated on any reference platform will be given lower priority than
+    problems with running Eclipse on a reference platform.
+  </p>
+  <p>
+    Eclipse 4.27 is tested and validated on a number of reference platforms. For the complete list, see <a
+      href="https://www.eclipse.org/projects/project-plan.php?planurl=https://www.eclipse.org/eclipse/development/plans/eclipse_project_plan_4_27.xml#target_environments">Target Environments in the
+      4.27 Plan</a>.
+  </p>
+  <p>
+    As stated above, <i>we expect that Eclipse works fine on other current Java VM and OS versions but we cannot flag these as reference platforms without significant community support for testing
+      them.</i>
+  </p>
+  <p>The Eclipse SDK is designed as the basis for internationalized products. The user interface elements provided by the Eclipse SDK components, including dialogs and error messages, are
+    externalized. The English strings are provided as the default resource bundles.</p>
+  <p>Latin-1, DBCS, and BiDi locales are supported by the Eclipse SDK on all reference platforms.</p>
+  <p>The Eclipse SDK supports GB 18030 (level 1), the Chinese code page standard, on Windows, Linux and the Macintosh.</p>
+  <p>German and Japanese locales are tested.</p>

+    will need to be ported to Eclipse SDK 4.27 APIs. Downward contract compatibility is not supported. There is no guarantee that compliance with Eclipse SDK 4.27 APIs would ensure compliance with
+    Eclipse SDK 4.26 APIs. Refer to <a href="https://wiki.eclipse.org/Evolving_Java-based_APIs"><em>Evolving Java-based APIs</em></a> for a discussion of the kinds of API changes that maintain contract
+    compatibility.
+  </p>
+  <p>
+    <strong>Binary (plug-in) Compatibility:</strong> Eclipse SDK 4.27 is upwards binary-compatible with Eclipse SDK 4.26 except in those areas noted in the <a
+      href="https://www.eclipse.org/eclipse/development/porting/eclipse_4_27_porting_guide.html"><em>Eclipse 4.27 Plug-in Migration Guide</em> </a>. Downward plug-in compatibility is not supported.
+    Plug-ins for Eclipse SDK 4.27 will not be usable in Eclipse SDK 4.26. Refer to <a href="https://wiki.eclipse.org/Evolving_Java-based_APIs"> <em>Evolving Java-based APIs</em></a> for a discussion of
+    the kinds of API changes that maintain binary compatibility.

+    <strong>Source Compatibility:</strong> Eclipse SDK 4.27 is upwards source-compatible with Eclipse SDK 4.26 except in the areas noted in the <a
+      href="https://www.eclipse.org/eclipse/development/porting/eclipse_4_27_porting_guide.html"><em>Eclipse 4.27 Plug-in Migration Guide</em> </a>. This means that source files written to use Eclipse
+    SDK 4.27 APIs might successfully compile and run against Eclipse SDK 4.26 APIs, although this is not guaranteed. Downward source compatibility is not supported. If source files use new Eclipse SDK
+    APIs, they will not be usable with an earlier version of the Eclipse SDK.
+  </p>
+  <p>
+    <strong>Workspace Compatibility:</strong> Eclipse SDK 4.27 is upwards workspace-compatible with earlier 3.x and 4.x versions of the Eclipse SDK unless noted. This means that workspaces and projects
+    created with Eclipse SDK 4.26, 4.25, 4.24, 4.23, 4.22, 4.21, 4.20, 4.19, 4.18, 4.17, 4.16, 4.15, 4.14, 4.13, 4.12, 4.11, 4.10, 4.9, 4.8, 4.7, 4.6, 4.5 and 4.4 can be successfully opened by Eclipse SDK 4.27 and upgraded to a 4.27 workspace. This includes both hidden metadata, which is localized to a
+    particular workspace, as well as metadata files found within a workspace project (e.g., the .project file), which may propagate between workspaces via file copying or team repositories. Individual
+    plug-ins developed for Eclipse SDK 4.27 should provide similar upwards compatibility for their hidden and visible workspace metadata created by earlier versions; 4.27 plug-in developers are
+    responsible for ensuring that their plug-ins recognize metadata from earlier versions and process it appropriately. User interface session state may be discarded when a workspace is upgraded.
+    Downward workspace compatibility is not supported. A workspace created (or opened) by a product based on Eclipse 4.27 will be unusable with a product based on an earlier version of Eclipse. Visible
+    metadata files created (or overwritten) by Eclipse 4.27 will generally be unusable with earlier versions of Eclipse.
+  </p>
+  <p>
+    <strong>Non-compliant usage of API's</strong>: All non-API methods and classes, and certainly everything in a package with "internal" in its name or x-internal in the bundle manifest entry, are
+    considered implementation details which may vary between operating environment and are subject to change without notice. Client plug-ins that directly depend on anything other than what is
+    specified in the Eclipse SDK API are inherently unsupportable and receive no guarantees about compatibility within a single release much less with earlier releases. Refer to <a
+      href="https://www.eclipse.org/articles/Article-API-Use/index.html"> <em>How to Use the Eclipse API</em></a> for information about how to write compliant plug-ins.

+      current configuration location as writable. The net result is that Eclipse will fail to start and depending on the circumstances, may fail to write a log file with any details. To work around
+      this, we suggest users experiencing this problem set their configuration area explicitly using the <code>-configuration</code> command line argument. (bug <a

+      the Eclipse install if you want to open more then one workspace at the same time (bug </a><a href="https://bugs.eclipse.org/bugs/show_bug.cgi?id=139319">139319</a>).

+  <p>If you need to launch Eclipse from the command line, you can create a symbolic link such as "eclipse". It should point to the eclipse executable inside the application bundle and takes the

+  <p>On Mac OS X 10.4 and later, you may notice a slow down when working with significant numbers of resources if you allow Spotlight to index your workspace. To prevent this, start System

+  </h4>
+  <p>Special care is required when a project in a team repository is being loaded and operated on by developers using Eclipse-based products based on different feature or plug-in versions. The
+    general problem is that the existence, contents, and interpretation of metadata files in the workspaces may be specific to a particular feature or plug-in version, and differ between versions. The
+    workspace compatibility guarantees only cover cases where all developers upgrade their Eclipse workspaces in lock step. In those cases there should be no problem with shared metadata. However,
+    when some developers are working in Eclipse 4.27 while others are working in Eclipse 3.x, there are no such guarantees. This section provides advice for what to do and not to do. It addresses the
+    specific issues with the Eclipse SDK.</p>
+  <p>The typical failure mode is noticed by the 4.27 user. 4.26 metadata is lost when a 4.27 user saves changes and then commits the updated metadata files to the repository. Here's how things
+    typically go awry:</p>
+  <ul>
+    <li>A user working in Eclipse 4.27 creates or modifies a project in a way that results in changes to a shared metadata file that rely on 4.27-specific information. The user then commits the
+      updated project files, including the shared metadata file, to the shared repository.</li>
+    <li><a
+      class="mozTocH4"
+      name="mozTocId226004">Another user working in Eclipse 4.26 or earlier shares this project from the same repository. The 4.27-specific information in the shared metadata file is not understood
+        by Eclipse 4.26, and is generally discarded or ignored without warning. The user modifies the project in a way that results in changes to the shared metadata file, causing the shared metadata
+        file to be rewritten without any of the 4.27-specific information. The user commits the updated project files, including the shared metadata file, to the shared repository. The user is
+        generally unaware that shared information has just been lost as a result of their actions.</a></li>

+      name="mozTocId226004">A user working in Eclipse 4.27 picks up the changes to a project from the shared repository, including the updated shared metadata file. The user may be unaware that
