Description _ lcincura 2004-11-02 15:53:54 UTC 
NetBeans IDE 200411020931 on java 1.5.0_01

I got the error while I was opening debugger views
very fast. I am not able to reproduce.

Huh, what's that?!? The class name is corrupted:
org/netbeans/spi/viewmoddl/UmknownTypeException

I grep the debugger sources for 'Umknown' and did not get any hits. This looks
like some very strange nonsense...

The java.lang.NullPointerException seems to be caused by multiple calls to
componentHidden() without preceding componentShowing(). - This is likely a bug
of core. But the API does not talk about whether the methods are called in pairs.
Can be easily fixed in our code.
Comment 3 Martin Entlicher 2005-05-06 12:47:33 UTC 
The NPE is fixed in trunk:

/cvs/debuggercore/src/org/netbeans/modules/debugger/ui/views/BreakpointsView.java,v
 <--  BreakpointsView.java
new revision: 1.8; previous revision: 1.7

The NoClassDefFoundError does not make sense to me. Closing as fixed, if you can
reproduce the NoClassDefFoundError with a clean build, please reopen.
