Blocked by find

I have a container object which wraps an objectdb database. There is a "putIfAbsent(String id, Object obj)" method which is synchronized and attempts to load an object by id using the EntityManager "find" method.

The thread dump looks like: ... Extremely slow performance may be the result of using zero size page cache, which causes cache purge to be invoked ...

Explorer bug ? Objects seem to be missing from database in Class view, but are present as references

objectdb-2.2.5_08 NetbeansID6.9.1+Glassfish3.01 I suspect the following is an Explorer bug. It is marked knowingly as CRITICAL by me because it makes the ObjectDB system unusable for a real project because it appears to be either database integrity corruption, or it just looks like it, which is just as bad. I attach a running project illustrating the problem, as well as screenshots. ... test case both in my logged output and by examining the result in the Explorer (which it seems is not at fault). regards, ...
