java version. In particularly, on some architectures it has a version
2:1.5 (i.e. >> 1:1.6, but using Java5). I suspect this can happen again
if we ever need to back out of a default change again.
If we want to use default-jdk in that way (i.e. let it have a version
that is useful for determining the Java major version), we need to have
a policy for dealing with """What happens if we need to "downgrade"
default-jdk from X to X-1?""".
