The agent currently sets java.library.path in the rhq-agent.bat/sh scripts. There is no way for us to keep the OS-default value, short of requiring the user to add the default directly into the script. We should see if we can stop setting java.library.path via the scripts - instead, we should append to the default java.library.path with the values the agent needs.
