Minor Description
I've done a maven-based approach to creation of a karaf environment using the same dependencies as the downloadable karaf does. In mine, the jaas.boot and karaf main jars are in the system/ hierarchy, not in lib. However, I have to have my deploy create an empty lib directory because karaf crashes with null pointer exception otherwise. This is because it does a for loop based on listfiles() for this directory, which crashes if it doesn't exist.
My wish is for this code (src/main/src/main/java/org/apache/karaf/main/Main.java , line 950) to first check existence of lib directory, and skip the for loop if there is no such directory.
