Bug 231342

Description Curtis Windatt 2008-05-09 13:42:40 EDT

Use a build that supports target weaving (M7 or later).
1) In your host, have one or more plugins
2) Launch a runtime workbench
3) In the runtime workbench, create or import a plugin that depends on one of the plugins in the host workspace
4) You should be able to open the class files with source under the Plug-in dependencies of your plugin in the runtime workbench.
5) Add a breakpoint somewhere inside your plugin that will allow us to step into code from one of the plugins in your host workspace.
6) Debug another runtime workbench
7) When you are at the breakpoint, step into code from the host workspace plugin
8) Source lookup fails

Reason:

In JavaSourceLookupUtil we are given the classpath entry that we need source for.  Debug is unable to get a java project for the classpath entry.  Without the project we cannot get the package fragment root and use JDT core's source lookup utility.  We revert back to using debug's generic DirectorySourceContainer, with subfolders turned off.  This fails because the source is in a src, src-ant, etc. subfolder.  Turning on the boolean flag to search subfolders is a workaround, but doing so might affect other users of debug.
