Re: Upgrade to 1.9; byteBuffer not set in WorkerThread

Hi,

Thanks for your response and sorry for my late response :-)

I'm using my own thread-pool (thus not the DefaultThreadPool) and thus
the byteBuffer is not set. I've implemented a work-around in my app:

WorkerThread wt = (WorkerThread) Thread.currentThread();
if (wt.getByteBuffer() == null) {
   wt.setByteBuffer(ByteBuffer.allocate(MsrpThreadPool.BUFFER_SIZE));
}

This I've put in the first filter in the chain, before the read()
operation is done by ReadFilter.

Thanks
Sebastian
