Connection problems on Db2

[Thomas Dudziak <to...@gmail.com>]

Hi,

after I adapted the unit tests so that they run on Db2 (i.e.
shortended the identifiers to have a maximum of 18 characters), I get
into other problems. After a couple of tests, I quite often get this
error:

Test configuration is standard (as in SVN) without changes. Could this
be a connection leak somewhere in the tests (or in OJB) ?
