Symptoms

Oracle Forms 12.2.1.3.0 with webstart using JRE 1.8_181 /191

When launching the application using Webstart, a Java message box opens that says "Application Error: Unable to launch the application."
This only occurs on client machines.  If executed in server machine it works perfectly.

Other Symptoms:

1. When installing a new version of JRE, the issue doesn't reproduce.
2. It works until the client machine is rebooted.
3. It will never work again until the JRE is uninstalled and reinstalled again.

Without webstart , forms works perfectly.

The URL has config=webstart

formsweb.cfg:
-------------
[webstart]
basejnlp=base.jnlp
webstart=enabled

Java Console :
--------------
java.lang.RuntimeException: java.lang.reflect.InvocationTargetException
Java Web Start Error:
#### java.lang.reflect.InvocationTargetException

Based on the error message in the Java console <Patch 27097419> was installed:

Forms 12c webstart: Java.lang.reflect.InvocationTargetException When Adding A Href In Jnlp (Doc ID 2360073.1)

but the patch did not resolve the issue.
