Unable to setup JBPM with java17

[Nivetha]

Hi,

    Getting below exception when starting the application through STS or running command standalone.bat from cmd prompt. I'm using JBPM 7.74.1,  JDK 17 & Maven 3.9.4. The same setup works fine with JDK 8.

What is the latest supported JDK version for JBPM 7.74.1.

Exception in thread "main" java.lang.ExceptionInInitializerError

The latest supported java is 11, but the error could actually be caused
by some of the 3rd party dependency Or set of dependencies which are not
compatible with java 17.
