That makes a great deal of sense. In our case, the native code is not in Maven at all; it's sitting in an outboard product installation directory along with 100 tons of NLP models and dictionaries. However, I'm trying to build something that someone else embeds into an arbitrary Java application (and I launch the OSGi framework for them). So, getting the temporary directory into java.library.path is not going to be straightforward. Options I see include simply changing the filename but using the same directory, or changing the Java code to know how to call System.load (which takes a pathname) instead of System.loadLibrary (which looks in java.library.path). > > david jencks > >> On Sep 17, 2016, at 3:57 PM, Benson Margulies <ben...@basistech.com> wrote: >> >> Has anyone out there succeeded shutting down the Felix container and >> having the classloaders GC to the point where native classes are no >> longer loaded, so that the same JVM can then start a new framework and >> again load the same native classes? >> >> To be a bit more precise, I have a bundle that includes some native >> classes.
