Hi!
We have a Netbeans Platform project with Ant build. Currently it is
hooked up with Netbeans 16 and Java 11. Everything is running smoothly.
However, we would like to transition to Java 17. Running the project
with JDK 17 stops to a problem immediately. Is it even possible to use
JDK 17 with Netbeans platform project?
The error:
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 @300ffa5d
