I created a test for DynamicImport-Package to check whether https://jira.jboss.org/jira/browse/JBCL-131 is actually working at the OSGi layer.
I fail to see how dynamic import and JBCL-131 are related?
JBCL-131 is an impl of OSGi' lazy bundle activation -- e.g. only invoke BundleActivator if some class from that bundle needs to be loaded.
