Java Web Start NumberFormatException while running

While trying to run Jar application using JWS (JNLP) launch. It has been giving me this error. Can't even find where is the mistake. Any directions would help.

If someone could tell me where is the potential location of this error, I could find post that code here.

Note: I have the latest Java 8 installed and working on Netbeans. The jar file works well if called manually, java -jar testTool.jar

Update:

Posting this here in case someone has that very same error, even with java 8 Update 101:

In our specific case, after a few hours of digging, the problem ended up being that NetBeans version 7.4 was putting some useless junk on the Codebase property of the jar's MANIFEST.MF; by going into the project properties, Application -> Web Start and then changing Codebase to User defined and Codebase Preview to *, the application started working correctly.

Please do keep in mind that we're using an applet instead of a JNLP application, so your mileage may vary.

Looks like a known issue... See Bug #236765

Upgrading your Java version as specified in the bug.
