Memory leak in JDBC persistence adapter

I think that we hit a regression in the Fuse 6.2 JDBC persistence adapter. The issue occurs only for the Fuse 6.2.Customer uses ActiveMQ's JDBC persistence adapter to persist messages to an Oracle 12c database. The memory usage of the message broker continuously increases in the processing of a large number of messages. The used memory is only freed after disconnecting the client from the broker.The test program as well as our broker configuration and a test protocol is attached.
