JBoss EAP 6.2 Performance Testing

When we tried to run 30 requests per second from a Netty server to Stateless Session EJB in JBossEAP 6.2 we get the following exception randomly.
And from internet we came to know that it is known bug. Is it resolved in JBossEAP6.2 or is there any work around for this?
