Names overlap between outer method args and anonymous class method args

[TropheusJ]

Specific case in Minecraft: (mojmap)
BundlerInfo.createForPacket:

static <T extends PacketListener, P extends BundlePacket<T>> BundlerInfo createForPacket(
		Class<P> packetClass, Function<Iterable<Packet<T>>, P> bundler, BundleDelimiterPacket<T> packet
	) {
		return new BundlerInfo() {
			// ...

			@Nullable
			@Override
			public BundlerInfo.Bundler startPacketBundling(Packet<?> packet) {
				return packet == packet ? new BundlerInfo.Bundler() {
					private final List<Packet<T>> bundlePackets = new ArrayList();

					@Nullable
					@Override
					public Packet<?> addPacket(Packet<?> packet) {
						if (packet == packet) {
							return (Packet<?>)bundler.apply(this.bundlePackets);
						} else if (this.bundlePackets.size() >= 4096) {
							throw new IllegalStateException("Too many packets in a bundle");
						} else {
							this.bundlePackets.add(packet);
							return null;
						}
					}
				} : null;
			}
		};
	}

Note the two packet == packet. Those are supposed to be comparing the addPacket / startPacketBundling packet args with the enclosing createForPacket one.

This is actually valid output that could be recompiled, but would result in incorrect behavior.
