Found 1 deadlock.
This error locks the pool. I have changed the max-active-time field to 300 sec. The deadlock occurs less but still happens. This version of MySQL normally fixes this problem of synchronisation of multiple thread that use the same connection but I'm not sure it is totally fixed. Do you have some feedback ?

How to repeat:
install resin 2.1.12 and set the max-active-time to 2 secondes. Do queries with a connection in a thead and leave the JDBC pool close the connection when the max-active-time is reached.
