Jeffrey Morlan commented on NETBEANS-906:
-----------------------------------------
Appears to be related to "tree.args =
tree.args.prepend(makeNullCheck(tree.encl));"
In JDK 8, this line of code is in Attr.visitAnonymousClassdefinition.
In JDK 10, it was moved to TransTypes.visitNewClass:
https://bugs.openjdk.java.net/browse/JDK-8044853
http://hg.openjdk.java.net/jdk10/master/rev/22d665f53a4a
In nb-java-x, it's in both places and tree.args is getting prepended twice.
