"==" can be used in this case as the method name is interned by JVM. 
Here is the comment for the field "name" from java.lang.reflect.Method:

   // This is guaranteed to be interned by the VM in the 1.4
   // reflection implementation
   private String              name;

BTW, in the old version of Class in the line 2766 there was already a similar check:

2764                 if (m != null &&
2765                     m.getReturnType() == toRemove.getReturnType() &&
2766                     m.getName() == toRemove.getName() &&
2767                     arrayContentsEq(m.getParameterTypes(),
2768                                     toRemove.getParameterTypes())) {
2769                     methods[i] = null;
