A Path is associated with a FileSystem and so the FileSystem must exist. 
For what you are doing, can you keep a cache of FileSystem instances to 
reduce the continuous opening/closing of zip files?

I'll need to get back you on the JAR URL syntax issue. The original zip 
provider used the "zip" scheme but was changed to the legacy JAR URL 
syntax to provide compatibility with JarURLConnection. Unfortunately 
that syntax is problematic, or will be if/when URI is updated to the 
most recent RFCs.
