Subject Re: JDBC connection pool memory leak

Update: Confirmed, everything looks good after running 46 hours.
I also started a second test yesterday using the same code but
Eclipselink instead of OpenJPA. It too looks good after 24 hours.

The only instances I could see increasing slowly were objects
called "compiledICHolderKlass", which I think are associated
with the inline cache of the Hotspot compiler. After some time
these instances stopped increasing, as expected.
