Lworld requires concrete classes to have either ACC_IDENTITY(0x20) or ACC_VALUE (0x40) to be set in the modifiers.
The ClassAccessFlagsRawTest was written prior to Valhalla and expects the ACC_SUPER (0x20) to be set.

The jdoc file for SUPERnotset does not set either bit and so a ClassFormatError is thrown.

The class file version number for SUPERnotset is 64.
There is no way to distinguish between main-line behavior and Lworld behavior.

java.lang.ClassFormatError: Illegal class modifiers in class SUPERnotset: 0x1
