OpenBSD java startup script helper
javaPathHelper is a script that java applications can use to provide a consistent and familiar method for launching java applications on OpenBSD. The use of JAVACMD, JAVA_HOME and PATH environment variables are well known methods for users to control which JDK is used to launch a java application. When a user sets up thier environment javaPathHelper will use it. No attempt is made to prevent the user from running an application that requires a particular JDK version with a lower version. When the user's environment has not be setup, javaPathHelper falls back to inspecting which JDK satisfied the RUN_DEPENDS for the package.
