Finally found the problem. It is in dbcp 1.2.2 version. (see this bug https://issues.apache.org/jira/browse/DBCP-244)
The fix is to change dbcp version back to 1.2.1 (in POM). Worked like a champ for me after two days of screwing with various options. Very hard to replicate on a db with any load as the wait_timeout doesn't expire. Stopping and starting the mysqld service did work for me as long as I was the first to hit it. Otherwise someone else would see the ugly stack trace. Ron Ron Anderson wrote: > > It will also fail after the mysql variable 'wait_timeout' expires which is > defaulted to 8 hours.
