Description Jan Chalupa 2004-05-18 21:23:57 UTC

[refactoring build #040518, JDK 1.5 beta-2 (b51)]

1. Started with a clean userdir
2. Opened 'openide' project
3. Set 'openide' CVS source root
4. Navigated to o.o.f.FileObject.java
5. Invoked Find Usages
6. Got InvalidObjectException: Object with 
MOFID ... no longer exists (see attachment #1 [details])
7. Another exception -- NPE form 
javaClassImpl.initChildren() -- was thrown too 
(see attachment #2 [details])

No usages were found. This worked in yesterday's 
build, although I was probably testing w/ 1.4.2 
then. Need to check.

Comment 4 Jan Chalupa 2004-05-18 21:33:26 UTC

Doesn't seem to occur with JDK 1.4.2_02.

Comment 5 Jan Becicka 2004-05-19 12:50:52 UTC

I cannot reproduce it even with JDK 1.5 b21.
Changing priority to P3.

Comment 6 Jan Chalupa 2004-05-19 13:18:23 UTC

Hmm, I can't reproduce it either now (JDK 1.5 b51), but it did occur
in a scenario as simple as described. Exception was thrown and Find
Usages didn't work -> P2.

Comment 7 Martin Matula 2004-05-19 23:29:09 UTC

The second exception is a duplicate of issue #43168

Comment 8 Jan Becicka 2004-05-25 08:24:11 UTC

First one is duplicate of issue 43693. The second one is duplicate of
issue 43168. Both are fixed.
