reopen HADOOP-18, at java.util.zip.CRC32.update ArrayIndexOutOfBoundsException

[Stefan Groschupf]

Hi,
sorry I'm not able to reopen an issue.
But we had this as well, may the sources change a bit but in the end  
it is the same error.
This happens until a own written map task. The job runs without any  
problems locally.

Any thoughts what this could be?
Can someone with privileges reopen the bug or should I create a new one?

Thanks.
Stefan
