I don't have a lot of information, but when starting a fresh install of Netbeans 6.01 with JDK 6.05 I get the following
[catch] at org.openide.util.RequestProcessor$Processor.run(RequestProcessor.java:986)
It might be good to know I disabled java's auto-update-scheduler (in Windows), but I'm not sure whether that relates to
Netbeans (is it the Netbeans autoupdater that crashes or a check for Java's updater that crashes?). I was unable to
find any options relating to the Java updater. Did not find a related issue either.
I can't seem to find any setting relating to the auto-updater of Netbeans, but I guess that's a feature request. Good
luck with it, sorry I can't give any more information. A nullpointer exception is bad either way :p
The stacktrace looks like similar to the one in the Issue 121289 so closing as the duplicate.
According to the issue, it is fixed in Patch 2 for 6.0.1 and certainly in 6.1/6.5.
