| <h1>3.0 JDT Launching Change Notes</h1> |
| <p>This document describes important changes in the 3.0 JDT launching support, relative |
| to the 2.1 release.</p> |
| <h2>API Changes</h2> |
| <h3>VMRunnerConfiguration contains environment</h3> |
| <p>Two methods have been added to the <code>VMRunnerConfiguration</code> type |
| to support the setting and retrieving of environment variables. |
| <p>Implementors of <code>IVMRunner</code> should call <code>VMRunnerConfiguration.getEnvironment()</code> |
| and pass that environment into the executed VM. Clients who use <code>DebugPlugin#exec(String[] |
| cmdLine, File workingDirectory)</code> can do this by calling <code>DebugPlugin#exec(String[] |
| cmdLine, File workingDirectory, String[] envp)</code> instead. Simply passing |
| in the result from <code>getEnvironment()</code> is sufficient.</p> |
| <h3>VMRunnerConfiguration and Bootstrap Classes</h3> |
| <p>In prior releases, the <code>VMRunnerConfiguration</code> had one attribute |
| to describe a boot path. The attribute is a collection of <code>Strings</code> |
| to be specified in the -<code>Xbootclasspath</code> argument. Three new attributes |
| have been added to the VMRunnerConfiguration to support VMs that allow for prepending |
| and appending to the boot path. The new methods/attributes added are:</p> |
| <ul> |
| <li><code>getPrependBootClassPath()</code> - returns a collection of entries |
| to be prepended to the boot path (the <code>-Xbootclasspath/p</code> argument)</li> |
| <li><code>getMainBootClassPath()</code> - returns a collection of entries to |
| be placed on the boot path (the <code>-Xbootclasspath</code> argument)</li> |
| <li><code>getAppendBootClassPath()</code> - returns a collection of entries |
| to be appended to the boot path (the <code>-Xbootclasspath/a</code> argument)</li> |
| </ul> |
| <p>The old attribute,<code> getBootClassPath()</code> still exists, and contains |
| a complete path equivalent to that of the three new attributes. However, <code>VMRunners</code> |
| that support the new boot path options should take advantage of the new attributes.</p> |
