BoneCP & Derby - How to properly shutdown

Question

I have:

BoneCP CONNECTION_POOL = ...;
CONNECTION_POOL.getConfig().setJdbcUrl("jdbc:derby:database...;shutdown=true");
Connection connection = CONNECTION_POOL.getConnection();
connection.close();
CONNECTION_POOL.shutdown();

However this results in the following exception:

3274 [com.google.common.base.internal.Finalizer] ERROR com.jolbox.bonecp.ConnectionPartition - Error while closing off internal db connection
java.sql.SQLException: Cannot close a connection while a transaction is still active.

How can I avoid this exception. I've tried every possible way I can think of...

Answer 1

Unless you are running v0.8.1-beta2 or greater, set "disableConnectionTracking" to true in your config.

Please note that you should also expect an SQLException from Derby after a SUCCESSFUL shutdown: http://db.apache.org/derby/docs/dev/devguide/tdevdvlp40464.html
