otoh, on re-reading https://wiki.ubuntu.com/MultiarchSpec

it is obvious that if the JDK is co-installable (which i think it is, 
given that all binary files are installed into arch-triplet paths), then 
the only proper value is "Multi-Arch: same".

so i return to field#1 and set B-D on "default-jdk:native" ?
