Initialize the locks properties with the installation path found using the classpath.  This is required when the user.dir variable of the JVM used to launch setup does not match the installation path.  This is what happens for example when the setup is launched using an external tool (like Abbot).

This only affects the setup and is safe (or at least does not make things worse) because the setup is figuring out the server root based on the jar files in the class path.
