Flavia Rainone commented on WFLY-5480:
--------------------------------------
The wrong size number appears at position 13 of the buffer after the buffer is copied, at MessageImpl.getEncodedBuffer. This wrong size is sent to the client and causes the Exception seen in the description above.
This method, MessageImpl.getEncodedBuffer, is invoked concurrently by two separate threads, both are sending a SessionReceiveMessage to the client (SessionReceiveMessage.encode).
In one of the threads, the buffer is sent and usedBuffer is set to true. In the other thread, after checking that usedBuffer is true, a new copy of the buffer is taken. The problem is in the copied buffer. While the original buffer, right after the copy, still contains the correct size at position 13, the new buffer, the copy, contains a garbage int at position 13.
I am trying to find whereas the problem is in netty, responsible for doing the copy, or is a race condition involving another thread changing the buffer contents, even if temporarily, and causing the copy to go bad.
Too bad I haven't found yet where is the native implementation of Unsafe at netty, the class responsible for performing the copy.
Maybe the messaging guys have a more specific opinion on what is causing this, let me know if that's the case.
