Comment 1 Svata Dedic 2001-09-14 13:36:13 UTC 
The cause of the NPE was, in fact, incorrect implementation of 
instanceOf().
Reproducable by invoking "Customize Bean" action on a java source 
node, provided that the class does not explicitly state "extends 
Object". Then serialize the bean somewhere, point to it and open the 
property sheet.

Fixed in dev trunk.
Comment 2 Jan Becicka 2001-10-03 16:02:23 UTC 
If I invoke Customize Bean Action on examples.advanced.MemoryView, 
NPE is thrown. I'm not sure if it belongs to clazz module ...
Comment 3 Jan Becicka 2001-10-03 16:05:24 UTC 
Created attachment 2826 [details]
NPE
Comment 4 Tomas Hurka 2001-10-04 09:28:38 UTC 
NPE reported as attachment #2826 [details] is unrelated to clazz module and in
fact is the one solved by issue #16004. Closing as resolved.
Comment 5 Jan Becicka 2001-10-05 11:20:41 UTC 
[200110050100] Verified
Comment 6 Quality Engineering 2003-06-30 16:43:45 UTC 
Resolved for 3.3.x or earlier, no new info since then -> closing.
