Description Simon Kent CLA 2001-11-23 06:15:23 EST 
When comparing the workspace version of a file, and the stream version, a 
NullPointerException is thrown when a period is typed after a non-commented 
piece of code.

e.g. public abstract Object forEachUserGroup(UserGroupClosure closure.);

When the . is placed after the word closure, the Exception is thrown, an 
internal error is generated and the corresponding log entry is:

1 org.eclipse.core.resources 4 Unhandled exception caught in event loop.

Comment 1 Erich Gamma CLA 2001-11-23 06:37:16 EST 
Problem is reproducable and seems to be related to auto activated content 
assist. However, when turning off auto activation the problem still exists.
Comment 2 Kai-Uwe Maetzel CLA 2001-11-23 10:13:52 EST 
Changed JavaSourceViewerConfiguration to not return a content assistant in the 
case of no editor.
