I am having an issue running the ISY Launcher.  I can start the admin.jnlp from each ISY without issue, but if I try to use start.jnlp I get the following error.  

This could be a Linux issue since I have not seen this before on my Mac. 

I have tried OpenJDK1.8,11,17 with the same error.  I am running IcedTea OpenWebStart 1.5.2

I have also seen this when attempting an alternate java web start:
