List soundFieldGroupLabelSubDescriptors = subDescriptors.subList(0, subDescriptors.size()).stream().filter(interchangeObjectBO -> interchangeObjectBO.getClass().getEnclosingClass().equals(SoundFieldGroupLabelSubDescriptor.class)).collect(Collectors.toList());

The first array entry of subDescriptors is null but should be filled with: GroupOfSoundfieldGroupsSubDescriptor (SMPTE ST377-4:2012) Key: {06, 0E, 2B, 34, 02, 53, 01, 01, 0D, 01, 01, 01, 01, 01, 6D, 00}

I think you have not implemented GroupOfSoundfieldGroupsSubDescriptor

Thanks for identifying the issue. Photon release 4.3.3 has fix for this.
