[Bug classpath/22642] java.util.zip.DeflaterEngine exception

[gcc-bugzilla at gcc dot gnu dot org]

I got an exception trying to pack this file with
GZIP (at DeflaterEngine.findLongestMatch).

Code to reproduce this error :

FileInputStream  inputStream = new FileInputStream("test.bin");
GZIPOutputStream outputStream = new GZIPOutputStream(new
FileOutputStream("test.bin.gz"));

byte[] writeData = new byte[inputStream.available()];
inputStream.read(writeData);
outputStream.write(writeData);

inputStream.close();
outputStream.close();

The attached diff file fixes this bug, but I want to investigate this a bit
further.  There is at least one other possible array overflow in the same
routine.

BTW, I think zlib has the same bug, but as there are no array bounds checks in
C nobody has noticed it.

Fixed in CVS.  I choose a different approach, so that the check I posted last
time is not necessary anymore.
