Description DougHW

Build Identifier: 20090619-0625

If source files have changed on the disk, trying to refactor->rename a file will crash if it has dependencies in those changed files.  This is not an uncommon scenario in team coding.  Instead of this, it should either prompt to refresh, or throw a meaningful error.

Reproducible: Always

Steps to Reproduce:
1.Delete a class that references some other class in your project
2.Do not refresh Eclipse
3.Try to Refactor->Rename the referenced class in Eclipse
4.Internal Error

Could you attach the .log ? If don't see any 
reference to NullPointerException in the
abbreviated traces you have posted - TIA.
