Description

We're currently trying to migrate a Netbeans platform project from java 1.8 to 17, and are running into multiple Netbeans related problems. When launching the application, the very first error that is occurring is the following: 

SEVERE: No way to find original stream handler for jar protocol
java.lang.reflect.InaccessibleObjectException: Unable to make field transient java.net.URLStreamHandler java.net.URL.handler accessible: module java.base does not "opens java.net" to unnamed module @448139f0

{}I've tried adding J-add-opens java.base/java.net=ALL-UNNAMED to the maven-compiler-plugin as a compiler argument in multiple modules to try and fix the problem, but it doesn't seem to work.
