Description

With JDK 16+28 / 17+1 NetBeans is showing IllegalAccessError:

 

java.lang.IllegalAccessError: superclass access check failed: class org.netbeans.lib.nbjavac.services.CancelAbort (in unnamed module @0x1af58186) cannot access class com.sun.tools.javac.util.Abort (in module jdk.compiler) because module jdk.compiler does not export com.sun.tools.javac.util to unnamed module @0x1af58186

 

Recompiling the JDK without the JEP 396 commit removes the issue, so it seems a consequence of it.

Adding

-J--illegal-access=permit

to netbeans_default_options in netbeans.conf restore the old behaviour.

 

Or adding

-J--add-exports=jdk.compiler/com.sun.tools.javac.code=ALL-UNNAMED -J--add-exports=jdk.compiler/com.sun.tools.javac.api=ALL-UNNAMED -J--add-exports=jdk.compiler/com.sun.tools.javac.jvm=ALL-UNNAMED -J--add-exports=jdk.compiler/com.sun.tools.javac.main=ALL-UNNAMED -J--add-exports=jdk.compiler/com.sun.tools.javac.comp=ALL-UNNAMED -J--add-exports=jdk.compiler/com.sun.tools.javac.parser=ALL-UNNAMED -J--add-exports=jdk.compiler/com.sun.tools.javac.tree=ALL-UNNAMED -J--add-exports=jdk.compiler/com.sun.tools.javac.model=ALL-UNNAMED -J--add-opens=jdk.compiler/com.sun.tools.javac.code=ALL-UNNAMED

helps too.
