My bad, carry on...
Tested with both 1.2.4 and 1.2.5.
An initialized bacnet4J device will easily handle the PropertyIdentifier.all for all of its objects, except for the 'device' object.
A little Wireshark exploration shows that a readPropertyRequest sent for the device object, with PropertyIdentifier.all, will receive as a response an error 'unknown property'.
Oops, it seems to only be a problem for version 1.2.5.
I suppose the bug was introduced in the somewhat major changes in the local device code.
Well, I just realized there was a version 1.3 now...
I'll check if there is a similar problem.
Nope! Everything is fine!
