Can you provide a detailed comparison of all the before and after
messages please. It seems to me you are rewriting some of the messages
in a way that changes the meaning.
! linkage_error1 = "loader constraint violation: loader
(instance of ";
! linkage_error2 = ") previously initiated loading for a
different type with name \"";
! linkage_error1 = "loader constraint violation: loader ";
! linkage_error2 = " wants to load class ";
! linkage_error3 = ". A different class with the same name was
previously loaded by ";
this does not describe the same situation!
