Bug 72183

Description Venkat Balabhadrapatruni 2004-08-18 13:25:50 EDT

After generating the model code using a Rose Model, I was editing the generated 
code, and when trying to save a change, the Eclipse 3.0 workbench hung with CPU 
pegged at 100%, and after waiting for about 15 minutes, I killed the workbench 
using Task Manager. This happened twice yesterday, I was able to bring up the 
workbench successfully after killing it using the Task list. There were some 
NullPointer Exceptions in the .log file as shown below:

At this stage I'm not really sure as to what has caused the Eclipse workbench 
to hang(I was in Java perspective), but both the times that happened, I was 
editing a generated Java class.
