I was importing a large number of plugins and got the following walkback. Eclipse appeared to have imported all of the plugins before this occured.

Looks like a problem in JavaProject.setRawClasspath0(JavaProject.java:1814).
What version of jdtcore are you using ? Actually I would rather want the exact source line (1814) in the corresponding jdtcoresrc.zip in JavaProject.java. Suspecting we have a library folder which matches a project directly...
I am using stable build 20011107. Line 1814 is the second line in this multi-line expression: indexManager.indexBinaryFolder( (IFolder) root.getUnderlyingResource(), (IProject) this.getUnderlyingResource());
For clarification, the multi-line expression is: indexManager.indexBinaryFolder( (IFolder) root.getUnderlyingResource(), (IProject) this.getUnderlyingResource());
This would indicate that the resource associated witha a Java project wasn't a IProject ? Sounds scary.
Closed, not reproduced in 6 months. Might have been a VM bug.
Never reproduced
