Description Michael Fraenkel

I asked to rename a class from MetaDataObject to MetaData.  It looks like it 
succeeded but I received the following exceptions when it was completed.

Could you please attach or send me the source of the offending compilation 
unit ?

Test case received, but could not reproduce.
Seems like an internal index error occurred, and from thereon the indexer was 
inconsistent.

Comment 3 Philipe Mulet

Which build did it occur in ?

Comment 4 Michael Fraenkel

Stable 20020214

Comment 5 Philipe Mulet

Closing, was never reproduced. Sounds like a VM/JIT bug.
