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
JNLP does not launch

Re: JNLP does not launch
Please send the logs after you launched your Jnlp with OWS v1.12.0.
