> The finalize method in AbstractIoFilterChain.java can possibly cause OOM error when the system is under very heavy load. The negative impact of "finalize" method can be found at:
> http://www.fasterj.com/articles/finalizer1.shtml
> AbstractIoFilterChain holds a reference to Session object which can hold a list of unwritten data. The deterministic run of Finalizer can very well cause memory not fred up on time under heavy load. And it can certainly cause very bad memory usage pattern and contribute to the overall heavy system load.
