Public bug reported:

The sun.net.httpserver randomly fails with
java.lang.ArrayIndexOutOfBoundsException: 4104 at
sun.net.httpserver.ChunkedOutputStream.writeChunk(ChunkedOutputStream.java:120)
- full stack trace below.

In essence a combination of writes to the class can end up leaving the
ChunkedOutputStream with exactly CHUNK_SIZE bytes in, and a further
write will under various circumstances overfill the buffer. This will
then cause an exception with the chunk is written.

This bug is documented at Sun/Oracle with bug number #6744329:
  http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6744329

The patch to fix it is here:
  http://hg.openjdk.java.net/jdk7/jsn/jdk/rev/b0378bb50d83

The bug at Sun marks this fixed as follows:
  Release Fixed	 7(b37), 6u18(b03) (Bug ID:2183328)

However, despite the 6u18(b03) tag above, the Ubuntu source the current
Lucide openjdk build (openjdk-6_6b20-1.9.13-0ubuntu1~10.04.1) does not
contain the relevant patch. My reading of the the relevant Java version
numbers (which might not be correct) is that it should contain this
patch (18<20), so it appears to have dropped somewhere.

As the effects are serious (random failure of http server), and the
patch is upstream, has been around since Sep 2008, and is obviously
correct, I am asking for an SRU.

I have verified this problem on Lucid. I have not verified on Maverick,
Natty, or Oneiric, but I expect it is the same. I have not verified it
on Precise, though I think that might have openjdk 7 on.
