{{The messageLength is negative, code is in MessageSerializer.java}}

{{}}

messageLength = MessageSerializer.bytesToInt(buffer.array());{{}}

{{}}

{{}}

{{and error is raised in }}

{{}}

ByteBuffer messageBuffer = ByteBuffer.allocate(messageLength);{{}}

{{}}

I tried to use minimal reproduce code to reproduce the error but I could not 
reproduce it. So *any ideas that when can it get negative messageLength*?  This 
error occurs occasionally in my program.
