Unused code

I am currently trying to re-implement a player based on Javax.soundand thus trying to understand the implementation here,
In the course of that process, I stumbled upon a piece of code that seems like it isn't used:

In the method `createLine()` The Assignment In StreamPlayer.java Line 481 makes the two assignments to sourceDataLine in L474 and L478 superfluos.

If this kind of comment isn't helpful, or the code here isn't maintained anymore, please let me know - I might just stumble upon something else.
