Describe the bug
after upgrade 1.17.1

To Reproduce

Edit:
Changing PacketContainer#getIntegerArrays() to PacketContainer#getIntegers() fixed the error for me.

@Day-Hawk are you sure that would fix the error?

It looks like you're using 1.17 and not 1.17.1, 1.17 uses ints, 1.17.1 uses IntList

So your fix is only correct for 1.17.0 and not 1.17.1 which is what the report is about.

@libraryaddict I updated the server yesterday to 1.17.1. It worked without errors. Due to the high number of errors, I have decided to work again without ProtocolLib, because the "NMS" packages have changed.

Added a modifier for the fastutil intlists: packet.getIntLists(); available in the latest dev build and repo snapshot

For the destroy packet you can use something like this in 1.17.1:

        PacketContainer packet = e.getPacket();
        List<Integer> entityIdList = packet.getLists(new EquivalentConverter<Integer>() {
            @Override
            public Object getGeneric(Integer specific) {
                return specific;
            }

            @Override
            public Integer getSpecific(Object generic) {
                return (Integer) generic;
            }

            @Override
            public Class<Integer> getSpecificType() {
                return Integer.class;
            }
        }).read(0);
