I have just released a new version of the nom.tam FITS library at
http://heasarc.gsfc.nasa.gov/docs/heasarc/fits/java/v1.0/
This version has one significant change: support for .Z compressed 
images.  I've decided that supporting this commonly used format
was a big enough change to push the library to V1.0!

Note the slight change in the location (v1.0 versus v0.9) from earlier 
releases.  Please let me know if you have any issues or problems.

Release 1.0

   - The major change to this release is support for .Z compressed images
     (at least on Unix platforms).
     This is implemented by invoking the uncompress command from
     within the Java code.  Uncompress must be in the user's execution
     path.
   - There is much more dynamic checking of the magic number of inputs
     to determine whether the input to the FITS constructor is compressed
     or not, and if compressed what the compression type is.
     The user can still confuse the program if they specify an
     incorrect value for the compression flag but in many cases it will
     get the compression right regardless of what the user specifies.
     Future versions may completely ignore the user specified compression
     flag though it will be left in for compatibility.
   - A new CompressTester class tests reading both types of
     compressed files and also does a test of all of the non-trivial
     constructors for Fits objects.
   - Handling of string inputs to the Fits constructor is changed so that
     instead of looking for a specific set of scheme prefixes, a string
     is first tried out as a URL and then as a file.
   - Bug fix to BinaryTable by A. Kovacs
