----------------------------------------------------
Yes, the ID class is a currently a subclass of ConstantCP which was originally
for the Fieldref, Methodref, InterfaceMethodref constants
That does not work properly; ID has 2 parameters but they are not class_index
and name_and_type_index as ConstantCP expects.
They are bootstrap_method_attr_index and name_and_type_index instead, and the
former is 0-based unlike class_index which is why the crash occurs
It looks like the intention in BCEL-209 was to share code, but the
InvokeDynamic instruction is not really compatible
