I've run into a problem.

With this change, `GZIPInZip.java` fails; the test is annotated like this:

/* @test
 * @bug 7021870 8023431 8026756
 * @summary Reading last gzip chain member must not close the input stream.
 *          Garbage following gzip entry must be ignored.
 */

Note the "Garbage following gzip entry must be ignored" line. This must be what bugs 8023431 8026756 refer to, but those bugs are not accessible ("You can't view this issue. It may have been deleted or you don't have permission to view it.") so I can't see what the problem was that required ignoring the extra garbage. Maybe you guys have access or know what this was about? Thanks.
