Using build 200307300800

I got the following NPE during auto build (I had loaded the latest code from 
HEAD, then the auto-build started). Content of my .log file.

What plugin are you talking about? There are a lot of eclipse ui plugins. I will
try to reproduce it.

It was most of the eclipse ui plugins. I'm working in another stream, but today 
I had to check some code from the HEAD stream. So I started that workspace, did 
a refresh with server (using the new sync view), there was a list of ui plugins 
that had changes, I just selected all of them, and did an update.

Unfortunately I could not reproduce. I suspect a JIT bug. The VM used was a IBM
JDK 1.3.1 VM.

Closed. The JIT in this VM is known for random NPEs.
