I'm experimenting with pydev. I have a couple of jar files a test jython project. I added them
to PYTHONPATH in project properties and the jar files show up in "External Libs" in project
browser. However, when I click on the "+" sign on the left side of the jar files, it expands
the Java packages properly on one of the jar files but on another jar file it only shows the
a few text files (License.txt, README.txt, rel-note.txt") but it doesn't show the Java class
tree. Any idea why this is happening?
