A potential null pointer dereference bug. Please confirm, much appreicated!

Hi,

We are developing a new static analysis tool for catching bugs in Java code. Upon scanning your codebase we find the following:

In Frame.java (stetho/src/main/java/com/facebook/stetho/websocket/Frame.java) line 41, if hasMask is false then maskingKey will be assigned null when passed to MaskingHelper.unmask(maskingKey, payloadData, 0, (int)payloadLen) the expression key[index++ % key.length] at line 14 in MaskingHelper.java will trigger a null pointer dereference.

Would you please take a look and confirm this is indeed a bug? Thanks a million!!!
