This forum is for the File Geodatabase API. There is no Java flavor, only C++, and multi-threaded
access is not supported.
I'd direct you to the appropriate forum, but you've already posted there and several other locations.
Please do not multi-post in the Esri forums. If you want the best possible response, you should
provide more information in the most appropriate forum, not an incomplete message in many forums.
A complete posting would have included the release and service pack, and the minimum code
sample which exhibits the problem, often with a trivial data sample. Bulk multi-posting will often
reduce the response rate or even get your postings removed, which is probably not what you want.
