If jar tool options are written with the new gnu style, then if the --release option is specified before any files are specified, the
 --release option is treated as an unrecognized option. The work around is to use the old style options until this issue is fixed.

These examples fail:
   jar --create --file=test.jar --release 9 test1

   jar --create --file=test.jar -C test1 .
   jar --update --file=test.jar --release 9 -C test1 .

And these examples do not fail:
   jar cf test.jar --release 9 test1

   jar -cf test.jar -C test1 .
   jar -uf test.jar --release 9 -C test1 .

   jar --create --file=test.jar -C test1 .
   jar --update --file=test.jar test2 --release 9 -C test1 .
