[ http://issues.apache.org/jira/browse/DERBY-1910?page=all ]
Fernanda Pizzorno updated DERBY-1910:
-------------------------------------
Attachment: derby-1910.diff
derby-1910.stat
The problem was being caused by some of the tests that kept a reference to a
connection object which prevented this objects from being garbage collected.
The attached patch (derby-1910.diff) fixes that problem.
I monitored the memory usage of the junit.textui.TestRunner JVM by using the
jstat with and without this patch. Without the patch the memory usage kept
increasing, and with the patch the JVM was able to garbage collect and the
memory usage stayed under 17000Kb. I have successfully run jdbcapi,
derbynetmats and derbynetclientmats with this patch. Can someone please review
it?
