Actually, Miranda methods should no longer be inserted in .class files. 
  The JVMS is clear on how method resolution is to take place, and 
adequately covers inheritance where an abstract class does not redeclare 
a method from a superinterface.  Also, the JLS makes no provision for 
adding the interface method to the abstract class, as it can affect 
binary compatibility differently than specified in JLS 13.  Neither 
jikes nor javac 1.4 emit Miranda methods.  The Jacks test suite has a 
couple of tests for this.

I believe that Classpath (and probably libgcj) still have a couple of 
documented workarounds in the source code in regards to Miranda methods.
