Description diegoeg 2011-05-13 08:47:16 UTC 
Dear friends,

I am developing a NetBeans Platform application that uses the built-in GUI builder.

For a while I have been able to shift between the Code view and the Design view without a problem. However, after several days, whenever I shirt to the Design view the IDE freezes out, with the hourglass mouse pointer. The rest of the programs running at that time continue working, and you can jump to one another no probs. But when going back to NetBeans (NB), the screen fails to paint. I have waited up to 5 minutes and NB is still frozen.

After the first freezing event, NB works fine provided you don't go into Design View, where it would freeze again. I have found no fix for this except to uninstall NB and reinstall again.

This problem has happened to me in two different computers, one running Windows XP, the other running Windows 7.

Any thoughts?

Best regards

D

Could you please generate thread-dump at the time of freeze, attach it here and reopen this issue ? http://wiki.netbeans.org/GenerateThreadDump
Thanks in advance.

This is a well known regression in JDK. It appears in JDK 6 update 21 and 22 (and in some "old" JDK 7 builds). It has been fixed in JDK 6 update 23. Therefore, I suggest you to update your JDK.

I am having the same problem using Netbeans 7.0 and 64-bit JDK 6 update 26....

Want to try with update 23 to see if OK - any ideas where to download from?

No, ignore me - I have discovered that Netbeans was using Update 21 instead of 26. Problem solved :)
