# frozen_string_literal: true

# Fact: java_libjvm_path
#
# Purpose: get path to libjvm.so
#
# Resolution:
#   Lists file in java default home and searches for the file
#
# Caveats:
#   Needs to list files recursively. Returns the first match
#   Needs working java_major_version fact
#
# Notes:
#   None
