[ JDK VERSION : 1.6 ]

While browsing a largeish java source file in a standard project.  Navigator display seems to be using 100% of the cpu.

javax.jmi.reflect.InvalidObjectException: Object with MOFID E9473653-6439-11DA-BB08-04255790AA77:00000000000023D5 no longer exists, class: org.netbeans.jmi.javamodel.Method$Impl

Comment 2 Jan Becicka 2005-12-12 06:56:55 UTC 
Probably duplicate of some issue? Do you check isValid()?
Comment 3 David Simonek 2005-12-12 13:03:00 UTC 
Hmm, I don't think it is a duplicate. Situation is that code in navigator is
running inside read transaction and checks validity of elements which lifetime
spans beyond one transaction:

ClassMemberModel, line 287: 
        repo.beginTrans(false);
        try {
            fireBusyChange(true);
            // check validity
            if ( this.clazz != null && !this.clazz.isValid () ) {
                this.clazz = null;
            }   

The element mentioned in exception comes from jmi call in the same transaction,
called after mentioned validity checks. 

After talk with jbecicka, I believe java navigation is using the API correctly,
so perhaps error is on jmi side, passing back. Please ask me if you need any
help, explanation of java navigation code, thanks.
Comment 4 Jan Becicka 2005-12-12 15:52:10 UTC 
It looks like different symptom of issue 63594. Javac died and left MDR in
inconsitent state. This should be fixed in latest dev build. Can you reproduce
this issue in latest dev? Thanks
