Description Darin Swanson

Expanded the jdi.jar in the Packages view (seems to have a problem with the
".classpath" entry?)

The jdi.jar is located in the org.eclipse.jdt.debug project.

Comment 2 Dani Megert

The test case is to enable/disable "Show version control".
The bug was that the label provider is reused. This is not possible because
ContentViewer.seLabelProvider calls dispose on the old one (test for identity
would be nice there).

Fixed. Available in builds >= I20020115
