mysql - 警告 [LocalManagedConnectionFactory :cleanup] Lock owned during cleanup:

Question

我们在 Jboss EAP 6.20 Beta1 上看到以下警告

2014-04-01 03:00:00,539 WARN  [LocalManagedConnectionFactory:cleanup] Lock owned during cleanup: EJB default - 7: java.lang.Throwable: Lock owned during cleanup: EJB default - 7

然而，在 Jboss EAP 6.0.1 上运行的完全相同的代码和设置不会产生此错误。

关于什么可能导致 Jboss EAP 6.20 Beta1 上的异常的任何想法？
