Summary

java/javavmwrapper: JAVA_VERSION does not work with openjdk25

Remove the hard coded lists of java version numbers to iterate over when
JAVA_VERSION is set to N+. Instead use N as the lowest boundary, and the
latest available JDK as the upper bound, and just scan for the highest
available version satisfying the requirement.

Ideally it should be possible to deduce the upper bound from the
available java versions in ${PREFIX}/etc/javavms, but leaving that for
later.
