JNLP does not launch

Hi team

Ever since we moved from Oracle Java to Java JDKs we are unable to open our JNLPs.

I have tried using OpenWebStart and IceTea Web to no avail...

originally I was getting messages about main classes but now I am getting new messages and not getting much value from the logs as I am able to discern.

I am using Amazon Corretto 21 JDK

Open Webstart 1.2.2

IceTea Web 1.8.7

Attached stage 1 and 2 logs as well as settings

The JNLPs are for IBM/Brocade Fiber Channel SAN switches as well as IBM/Cisco Fiber Channel switches

Please use the latest version 1.12.0 of OpenWebStart.

Please send the logs after you launched your Jnlp with OWS v1.12.0.
