Java EE的长事务时间解决方案？

A problem I've encountered a few time in my career is in a tiered service architecture a single downstream system can bring down the entire client application if it gets into a state where all its threads are consumed on a deadlock or some sort of infinite loop bug in that system. Under these conditions the server socket on the Java EE server is still accepting and queueing requests from client applications. This causes the client application to use up all its threads waiting for responses from properly established socket connections. Then all users are locked out of the system as their requests are also being queued.A problem I've encountered a few time in my car
