Automatically created datasources leaking classloader

[Trevor Stevens <ts...@me.com>]

When OpenEJB loads a persistence.xml if a non-jta-data-source element is not present it automatically generates a datasource to place there. The issue that I am seeing is that the datasource is never closed when the webapp containing that persistence.xml is undeployed. As a result the webapp's classloader is leaked since the datasource that was auto-created has a reference to the webapp's classloader. Would it be possible to have OpenEJB either close auto-created datasources when the webapp is unloaded or create those datasource using another classloader?
