****************************************************************
When a class loader locates a resource in a zip file, it
returns a URL with a wsjar protocol handler.  If that URL is
used as the context for constructing a new URL for an entry
that does not exist, URLConnection.getInputStream will return
null rather than throwing a FileNotFoundException like the jar
protocol handler.

Problem conclusion

The wsjar protocol handler is changed to throw
FileNotFoundException from URLConnection.getInputStream when
the JVM custom property
com.ibm.ws.classloader.getInputStream.enableIOException is set
to true.  If the property is unset or set to false, then the
current behavior of returning null is retained.
The fix for this APAR is currently targeted for inclusion in
fix pack 6.1.0.21.  Please refer to the Recommended Updates
