[TIMOB-2933] Android: facebook - java errors when using graph api publish (though publish does succeed)

Sadly, this is inside Facebook's android SDK and android code itself. It's not an exception that surfaces (it's quelled internally by Android code and displayed just for logging purposes by them, thus the comment "Attempt to cast generated internal exception:").

Technical reason:

FB checks every key inside a Bundle to see if it happens to be a byte array. They do that by iterating over each key and calling if Bundle.getByteArray(key) == null .... If the value associated with the key is not a byte array, then null is returned, which is fine for FB's purposes. Alas, Android's Bundle code decides to log the fact that the call -- internally -- also caused them to have a ClassCastException. They don't re-throw that exception -- they just logcat it and return null, which FB programmers are counting on (and rightly so, given that the documentation for getByteArray says "Returns the value associated with the given key, or null if no mapping of the desired type exists for the given key or a null value is explicitly associated with the key."

In a nutshell: this is not our code and the ugly logging -- in this case -- is not a sign of anything gone wrong. Android internal code has decided to log an exception that they don't throw.
