need to fiddle with it. The default case statement, "do nothing"
is all fine here.
Facter::Util::Resolution.with_env is long time gone since
Facter > 2.x. That was even longer before introduced by me.
Remove that OpenBSD special case in the java_version fact,
and assume that $PATH is properly set in order to find
the 'java' binary.
Additionally confine the java_default_home and java_libjvm_path
to OpenBSD kernel as well. Add some flesh to the java_default_home
fact to allow it to find the java binary.
* dirname containing base directory of java
* e.g. java binary is `${::java_default_home}/jre/bin/java`
* dirname containing `libjvm.so`
* Most people will use this for LD_LIBRARY_PATH
