Greetings.

Winp issue #46 filed for this as well, it was suggested to also file a Jenkins bug.

I am getting an exception from winp (v1.25, bundled with Jenkins LTS 2.73.3), specifically from Native.java, line 144.

I believe it is coming from the getJarFile() method. There is an if-statement on line 166 that returns null if the url doesn't start with jar: or wsjar:.

In my case the url starts with zip: so it is failing the test & coming up null.

This problem surfaced while email-ext was attempting to connect to the SMTP server.

Does this need a code fix or is there something I can do on my end to workaround the issue?
