test fix for bug #1642285

Try importing from a jar which contains a .class file which is completely empty (0bytes).
Make sure that the bad class file is skipped while good class file is processed.

Although this is an aberrant .class file, it has been seen in the wild (see bug report, found in a weblogic
jar).
