Version 1.10: Launch Error: Could not launch JNLP file. The application has not been initialized

[patrice0]

Hi,

We've used OpenWebStart for our application for several years (since version 1.2 or so). It no longer starts correctly with OpenWebStart version 1.10. The error is

net.sourceforge.jnlp.LaunchException: Fatal: Launch Error: Could not launch JNLP file. The application has not been initialized, for more information execute javaws/browser from the command line and send a bug report.

where the relevant part of our code is

ClassLoader cl = SomeLocalClass.class.getClassLoader();
return cl.getResourceAsStream(System.getProperty(resourceName));

The file "resourceName" is in the .jar file, and can be found without issues up to version 1.9.1 (downgrading OpenWebStart to version 1.9.1 allows the application to run again). The error occurs on both Windows and Linux. I can provide the entire output from OpenWebStart if it's needed to help diagnose the issue (but, unfortunately, not the .jar file). Thank you,

Patrice

The jar file is not relevant.
But a complete log file (both stage 1 and 2) would be helpful.

Either past them here or send them to [email protected] with a short message linking to this GH issue.

I have emailed the log file.

Adding a two lines program that triggers the issue here (it's been emailed as well).

The problem is still present on release 1.10.1. Will it be fixed in the next release?
