FULL PRODUCT VERSION :
java version "1.5.0_05"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_05-b05)
Java HotSpot(TM) Client VM (build 1.5.0_05-b05, mixed mode)


ADDITIONAL OS VERSION INFORMATION :
Win XP Pro w/SP2

A DESCRIPTION OF THE PROBLEM :
GZIPOutputStream.finish() apparently closes the file; documentation specifically says it does not close the file. File cannot be written to after execution of finish().

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
access a large file, more than one megabyte in length. http://setiathome.berkeley.edu/stats/user.gz (uncompressed) will do.
execute Split x:/dir/fileName.xml x:/dir
  Program will crash saying Error writing X:/dir/fileName1.gz
Reason: write beyond end of stream


EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
  Program Split should run to end.
ACTUAL -
  Program crashed, saying Error writing O:/Temp/user1.gz
Reason: write beyond end of stream

ERROR MESSAGES/STACK TRACES THAT OCCUR :
Error writing O:/Temp/user1.gz
Reason: write beyond end of stream

REPRODUCIBILITY :
This bug can be reproduced always.
