Test failures on TRUNK - ArrayIndexOutOfBoundsException in o.a.h.h.regionserver.HStore.compact

I think Hudson is still hung up on the failure in TestFilter there.

[junit] Test org.apache.hadoop.hbase.regionserver.TestCompaction FAILED
[junit] Test org.apache.hadoop.hbase.regionserver.TestHRegion FAILED
[junit] Test org.apache.hadoop.hbase.regionserver.TestSplit FAILED
[junit] Test org.apache.hadoop.hbase.util.TestMergeTool FAILED

Same error on all but TestMergeTool:

java.lang.ArrayIndexOutOfBoundsException: 2

For TestMergeTool:

'unit.framework.AssertionFailedError: 'merging regions 0 and 1' failed
