Similar if not the same that #98

[CalebFenton]

The obvious bug here is the ClassCastException. That's worth looking into.

The problem with the method not getting deobfuscated may be theoretically unsolvable, so really tricky to fix in general. The question for that part is: do you think that method should be optimizable? Are there any obvious loops that rely on file / network IO that may never terminate?

[CalebFenton]

The ClassCastException was caused by the array item being of type Ljava/lang/Object; and APutOp.throwsArrayStoreException() assumes the array item type is always of an "obvious" array type, like "[Ljava/lang/Object;" but this isn't a good assumption. Technically, all arrays, including primitive arrays, are also Ljava/lang/Object;s.

There's no real way to fix the halting problem, which may be the cause of the null graph. Feel free to re-open if you experience an additional bug.
