OutOfMemoryError on search after update on DB created with DB Doctor

In order to explore the OutOfMemoryError we will need more ...

InternalException during producer/consumer scenario

Hi, I'm trying to use objectdb in a producer/consumer scenario.

Version 2.2.1 fixes these problems. Thank you for this report. ObjectDB Support ObjectDB - Fast Object ...
