Hi Jörg,

Thanks for testing - I logged a JIRA issue for this and put the
details in that ticket:

    https://issues.apache.org/jira/browse/IO-253

The short summary is that I believe the WriterOutputStream failure is
a bug in IBM's JDK 1.6 and the memory problems with
FileCleanerTrackingTestCase I can't investigate because I don't have
access to IBM JDK 1.5 - but I believe this is an issue in the test
rather than in FileCleanerTracking.

It would be nice for these tests to pass on IBM's JDKs - but I don't
think it should block the release of Commons IO 2.0.

Niall
