NullPointer exceptions in plug-in: "org.eclipse.ui.workbench"!?! [message #330960] Tue, 19 August 2008 11:20 Go to next message
Eclipse UserFriend
I constantly get most annoying NullPointerExceptions in eclipse core
plugins. This seems to have top do with the console view, specifically
when bringing up a new (or recycle an old) console view - though I can't
say reliably. What is a good way to collect useful info so that this can
get fixed soon?

This is on Ganymed...
