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.
