Hello,
i'm developing a Refactoring Plugin with Eclipse 3.2.2
(eclipse.buildId=M20070212-1330, java.version=1.6.0_01).
The Refactoring changes the code of a JUnit4-Testcase. Because the
added code requires some additional classes, also a few libraries
are added to the project's classpath in a Classpath Container.
When the Refactoring is done, everything works fine. When i
select "Edit -> Undo Refactoring", the changes are taken back,
but Eclipse throws a NullPointerException. The error message is
"Problems occurred when invoking code from plug-in:
org.eclipse.ui.workbench".
The exception stack trace is as follows:
java.lang.NullPointerException

What could be the reason for this error? It's very hard to associate this
exception with the code in my plugin. I would be glad for ever hint!
Thanks,
Thomas
