Build 20020409 Bug 13466 shows that when a JavaModelException that wraps a CoreException is thrown, the UI doesn't extract the CoreException info. It should use JavaModelException.getException() to extract this info and thus display the status of the CoreException. This would allow faster debugging and this would avoid moving bugs to JDT/Core when it is a Platform problem.
I agree that the wrappered information should not be lost. However, this should be done by the JavaModelException transparently, i.e., when a CoreException is wrappered then the getStatus call should be forwarded by the JavaModelException to the wrappered CoreException. This is also the approach taken in Throwable in JDK 1.4 were there is support for exception wrappering in Throwable directly. Moving back to JDT core.
When a JavaModelException wraps a CoreException, the status of the CoreException is now remembered instead of creating a JavaModelStatus.
