Oh yes sorry i guess it s to early in the morning… I was stuck in between its okay and should not be a problem xD just to verify that your roomservice is working, i made a build for it yesterday evening and it worked 
if you want i can check for my jdk version, but that is why we suggested to build for a supported device the same android version as you aim to build for the unsupported device, that way you would have noticed the missing jdk package before building…
