It shouldn't. Java erases types when writing bytecode: http://docs.oracle.com/javase/tutorial/java/generics/erasure.html Essentially, the above code is wrong based on Java's implementation because the bytecode is ending up 2 unwrap methods that both take "List". I would suggest fixing the code to change the method names. It may be working at runtime with 6 for now, but can break any time.
