Danushka Menikkumbura commented on QPID-2902:
---------------------------------------------
Initially it looked as if it was an encoding issue but when I had a closer look
I could see that the issue lied in the frame assembler.
Actually the message segments generated in the Assembler.java (lines 158-162)
were corrupted as a result of scrambled frame body content.
Assembler.frame() receives frames of a given message that are stored in a list
and assembled and sent forward as soon as the last frame is received. The frame
body content gets corrupted during this transition. This is due to a flaw in
the frame body content formation logic in the broker transport input handler.
The InputHandler uses a fixed-length ByteBuffer which gets filled with incoming
data stream and frame content is formed by slicing this buffer. When a
ByteBuffer is sliced, the new buffer is a shared subsequence of the original
buffer's content and changes to the original buffer is visible in the new
buffer and vice versa. Because of this reason, frame content stored in the
segment gets corrupted and as a result the content of final AMQP message gets
corrupted.
Thanks,
