Description

I'm not sure how to reproduce the problem, I just got this dialog as I was starting, stopping, or running the debugger. But here's the description of what I saw and the stack trace:

This is from build 266626, installed yesterday.

I just had a "Multiple problems have occurred" dialog pop up with two of the same errors reported. At the top, it says "Evaluating Flex expression..." and in the details area it says "An internal error occurred during: Evaluating Flex expression...". java.lang.NullPointerException

I wasn't doing anything fancy when this happened. I think I was just either starting or stopping a debug run.

I checked the error log and there were two stack traces at the bottom that seem to correspond to these two identical errors:

!ENTRY org.eclipse.core.jobs 4 2 2010-01-13 13:35:16.485
!MESSAGE An internal error occurred during: "Evaluating Flex expression...".
