Description Alexander Maletz

2007-12-08 05:24:40 EST

Build ID: M20071205-0800

Steps To Reproduce:
1.Navigate->Open type
2.Start typing letters (any)
3.Exception dialog is shown

This did not occur in Eclipse 3.1.1. Started happening for me only in 3.3.2 builds. Looks very similar to bug 179199, but does not seem to be the same (exception is thrown from createTypeFromJar). There is quite a few jars that are referenced by many projects. Removing some of them fixes the problem, but I could not figure out WHAT in these jars causes crash.


More information:

eclipse.buildId=M20071023-1652
java.version=1.6.0_03
java.vendor=Sun Microsystems Inc.
BootLoader constants: OS=win32, ARCH=x86, WS=win32, NL=en_US
Command-line arguments:  -os win32 -ws win32 -arch x86


The trace is following:
java.lang.NullPointerException
