[eclipselink-dev] Memory leak/consumption in ExpressionBuilder

[Alexander Lehmann <a.lehm@xxxxxx>]

Hi all,

I just analysed a heap dump of our production server and found a
RepeatableWriteUnitOfWork consuming most of the heap space. This is
nothing special per se but this UOW seems not to be active anymore.
The path to gc root shows it's only referenced by an ExpressionBuilder
which itself is located somewhere deep inside the meta-model (see
attachment).

Could it be that the setStatement() Method of the ExpressionBuilder
was called with an active Statement and later this statement was not
cleared from the ExpressionBuilder?

Thanks in advance for any hints.

Best regards
Alex
