Comment 1 Jan Becicka 2004-08-10 13:22:27 UTC 
This issue is surprisingly duplicate of issue 47046. NPE is thrown,
becuase DataObject (Midlet.java) is not valid.

*** This issue has been marked as a duplicate of 47046 ***
Comment 2 Jan Becicka 2004-08-10 14:21:04 UTC 
Reopening to implement workaround.
Comment 3 Jan Becicka 2004-08-10 14:23:27 UTC 
Better handling of invalid objects:

Checking in JMManager.java;
/cvs/java/javacore/src/org/netbeans/modules/javacore/JMManager.java,v
 <--  JMManager.java
new revision: 1.43; previous revision: 1.42
done
