@jinossy ,
Thanks for posting your test results.
I have ran test cases with JDK 1.6 and JDK 1.7, and I did not find rpc hang
issues on TestAsyncRpc. Can you provide the details on your test environment?
By the way, I have removed the HashedWheelTimer in TaskRunnerManager,
because netty 4 does not accept the Timer object when creating
ReadTimeoutHandler instance. Netty 4 uses internal scheduler when catching up
the timeout event.
Anyway, thank you again, and I will look through these timeout handlers. In
some cases, I found that netty 4 does not create the time-out event.
> Upgrade to Netty 4

> Currently, rpc package uses Netty 3. Netty 4 is more stable and will get
> significant performance benefits. We need to upgrade Netty version to 4.
