All Implemented Interfaces:

@CustomUserValue public class CompareClassNameEquals extends edu.umd.cs.findbugs.bcel.OpcodeStackDetector
In a JVM, Two classes are the same class (and consequently the same type) if they are loaded by the same class loader, and they have the same fully qualified name [JVMSpec 1999]. Two classes with the same name but different package names are distinct, as are two classes with the same fully qualified name loaded by different class loaders. Find usage involving comparison of class names, rather than the class itself.
