Description Petr Nejedly 2004-11-15 09:58:19 UTC 
Scenario from issue 51384.

I've found extraordinary increase in number of
Integer instances and HashMap$Entry
instances (tens of thousands) and traced it to the
MdrStorage singleton.
MdrStorage keeps track of all ever created
instances of ValuesObject.
There is a way to register new instance of
ValuesObject (one ValuesObject instance
per one storageId), but there is no way of
unregistering it, so I found >300 instances
of ValuesObject registered. Each ValuesObject
keeps quite large list of values and a map
which maps values to integers. These objects are
kept even after closing all related projects.

Comment 2 Petr Nejedly 2004-11-15 15:06:15 UTC 
I can confirm that ValuesObject instances get properly freed and most
of Integer instances as well in current trunk sources.
