That's because in Java you cannot cast a Type[] into a ST[] (although you
can cast a Type into a ST).
There are some convenience methods in the superclass:
return getTypedField(1, new ST[0]);
// Alternatively use Arrays.copyOf
// instead of return (ST[]) super.getField(1);
return getTypedField(2, 0);
// instead of return (NM) super.getField(1, 0);
