Subject: Re: [configuration][ALL] compatibility issues with hsqldb

I had the same problem in Commons Resources recently. We had been using
hsqldb 1.7.1 (which I think was OK with JDK 1.3) - but the problem was it
shut down the database if all connections were closed. I fixed an issue in
Commons Resources to close connections properly and found the tests failed -
upgraded to hsqldb 1.7.2.2 (same version as Configuration) and hit the same
JDK 1.4 issue. I fixed it, by just not running the one JUnit test case that
uses hsqldb if the JDK was less than 1.4:
