The change from !isPresent() to isEmpty() suggests this might be a Collection or similar type. If this is an Optional, use !isPresent() for clarity and consistency with Optional API patterns.

Suggested change

	if (inclusionProof.getAuthenticator().isEmpty()) {
	if (!inclusionProof.getAuthenticator().isPresent()) {

The error message incorrectly refers to 'burn commitment' but this is in the context of a nametag transfer operation. The variable response should be nametagTransferResponse.getStatus() to match the actual operation being performed.

Suggested change

	throw new Exception(String.format("Failed to submit burn commitment: %s",
	response.getStatus()));
	throw new Exception(String.format("Failed to submit nametag transfer commitment: %s",
	nametagTransferResponse.getStatus()));
