 // For bytecodes not produced by javac together it is possible that a method does not override

+// For public and protected methods: if they override a superclass, they will
+// also be overridden themselves appropriately.
+// Private methods do not override and are not overridden.

+// e.g. P1.A, pub m
+// P2.B extends A, package private m
+// P1.C extends B, public m

+// Therefore: all package private methods need their own vtable entries for
+// them to be the root of an inheritance overriding decision
+// Package private methods may also override other vtable entries
