+This directory is the standard java classpath directory.
+Any jar in this folder will be part of the main classloader used to load Karaf.
+However, in OSGi, classes defined in this jar won't be available to other bundles
+unless one of the org.osgi.framework.system.packages.extra or
+org.osgi.framework.bootdelegation property in the etc/config.properties file
+is modified to export or delegate the packages.
+Please refer to the OSGi Core Specification for more informations on those
+properties and the OSGi classloading mechanism.
