Bug 362471

Description Claudio Nieder 2011-10-31 07:33:00 EDT

Build Identifier: I20111028-1100

I was editing the file for a while without any troubles when suddenly it started to pop up a "NullPointerException" dialog every time I wanted to select something in the editor.

Every time this happens the following error gets written:


eclipse.buildId=I20111028-1100
java.version=1.6.0_27
java.vendor=Apple Inc.
BootLoader constants: OS=macosx, ARCH=x86_64, WS=cocoa, NL=en_US
Framework arguments:  -keyring /Users/claudio/.eclipse_keyring -showlocation
Command-line arguments:  -os macosx -ws cocoa -arch x86_64 -keyring /Users/claudio/.eclipse_keyring -showlocation
