Hi Robert, this 3rd party library is a bit complicated ... from what I understood it hasn't been developed with OSGI in mind (but rather for application server use), and fiddles around with classloaders etc. I was told that the this library internally internally loads classes from the JVM, effectivly ignoring the OSGI classloader partially.
Our idea is allow this bundle (we packaged the library into a single bundle) to use the javax.activation classes from the JVM directly, and ignore the sling bundle for it; all the other bundles are supposed to use the sling bundle though. This would have the least impact to the rest of the system. Today we tried to export the JVM classes by fragment bundle with the export statement "javax.activation;version=0.0.1" and import this version from the bundle; while this made the bundle use the fragment as we intended, all other bundles were now using this fragment as well (which was not our plan). Do you see any other option we can try? Am Mo., 13.
