“Connection is not associated with a managed connection” After changing MySQL's JDBC Driver

Question

I have a webapp running on jboos 6.0.1.

After changing MySQL's JDBC Driver from 5.1.10 to 5.1.33 i'm getting sometimes the following Exception :

javax.ejb.EJBTransactionRolledbackException: Cannot open connection
        at org.jboss.ejb3.tx2.impl.CMTTxInterceptor.handleInCallerTx(CMTTxInterceptor.java:148) [:0.0.2]

It seems that a modification made in the driver between the versions 5.1.13 and 5.1.14 caused the problem. ( it is may be and old bug that didn't happens because the driver was permessive =)

我使用了此JVM参数-Dhibernate.jdbc.use_streams_for_binary = true，现在可以正常使用！
