This JAR is not corrupted but Mozilla Firefox included a "security" feature affecting JARs several years ago, the content of the JAR is more or less wrapped into a ZIP... which leads to a JAR unusable as is. Rather download the whole archive and extract the JARs from it:

If you still have the same error, then the JAR is really corrupted. The reported bug was already fixed a long time before JOGL 2.1.3 was released, it should work but maybe you have found another bug.
