>> j.l.i.InvokerBytecodeGenerator::isStaticallyInvocable doesn't distinguish between VM anonymous classes and ordinary classes. In some very specific circumstances (VM anonymous class declared in one of predefined core packages), it can consider a member of VM anonymous class as statically invocable and symbolically reference it from generated bytecode. It's wrong because such class can't be looked up by name and the attempt to run such code ends up with NoClassDefFoundError.
