Java method SenderKeyDistributionMessage.getDistributionId() returns wrong value

[imb591]

For example:

var distribution = java.util.UUID.fromString("01234567-89ab-cdef-fedc-ba9087654321");
var senderKeyStore = new org.signal.libsignal.protocol.groups.state.InMemorySenderKeyStore();
var groupSessionBuilder = new org.signal.libsignal.protocol.groups.GroupSessionBuilder(senderKeyStore);
var address = new org.signal.libsignal.protocol.SignalProtocolAddress("addr", 1);
var message = groupSessionBuilder.create(address, distribution);
System.out.println(String.format("distribution = %s, message.getDistributionId() = %s, store has distribution %s, store has message.getDistributionId() %s",
                distribution,
                message.getDistributionId(),
                senderKeyStore.loadSenderKey(address, distribution) != null,
                senderKeyStore.loadSenderKey(address, message.getDistributionId()) != null));

As far as I understand, it should print

distribution = 01234567-89ab-cdef-fedc-ba9087654321, 
message.getDistributionId() = 01234567-89ab-cdef-fedc-ba9087654321,
store has distribution true,
store has message.getDistributionId() true

but with libsignal 0.35.0 it seems to read something at a wrong offset and prints

distribution = 01234567-89ab-cdef-fedc-ba9087654321,
message.getDistributionId() = 60000000-0000-0000-0123-456789abcdef,
store has distribution true,
store has message.getDistributionId() false

Aw shoot, you're right. We have a mistake in the untyped bridge layer, never noticed because the Android app doesn't need to use that API. Will fix in the next release.

Fixed in v0.37.0, thank you!
