I don't think so. But shouldn't it be enough to simply use
JAVA_HOME/jre/lib? If JAVA_HOME isn't defined, you can check the
location of the java binary as fallback and go one level up from
there. But if that still doesn't work, just throw an error and ask the
user to define JAVA_HOME properly.

The fun is that there are different definitions out there of where
JAVA_HOME should point to, but I think it has more or less settled to
the top level of a JDK installation.
