The entries and stream methods have been discussed here several times. 
The conclusion was that they would continue to enumerate or return a 
stream over all entries in the JAR file.  A new versionedStream() method 
was proposed and I agree is needed, it just didn't make it into Java SE 
9. Now might be the time to put it back on the table.
