------- Additional Comments From dmarshall@vmsystems.net  2005-05-06 13:09 -------
I've encountered the same deadlock and have a couple of additional comments: the
bug is only when using PoolingDriver and a setting of minIdle > 0 in the
GenericObjectPool configuration.

Suggested interim workarounds:
a) set minIdle = 0 in your configuration for the GenericObjectPool
b) if you know you are connection pooling within the application code, retrieve
a connection as follows:
    ObjectPool connectionPool = poolingDriver.getConnectionPool(name);
    Connection conn = (Connection)connectionPool.borrowObject();
This second method will allow you to have minIdle > 0 while avoiding the
deadlock code path between threads.
