When trying to extend jython-standalone-2.7.2.jar using the `jar` command I get this error:

    jar: Package org.objectweb.asm.signature missing from ModulePackages class file attribute

It seems that the problem is caused by module-info.class file at the root of the jython-standalone-2.7.2.jar. It doesn't exist in jython-standalone-2.7.1.jar and with it I get no problems. Removing the file also fixes the problem with 2.7.2.

This seems to be dependent on Java version, environment or something similar. I'm not the only one in our project who has encountered this problem, but there are also others who aren't affected. For more details about our exact case see:

It's easy for us to remove the problematic module-info.class file when building our jar package. I hope someone from the Jython project could comment is doing that safe.
