A given native library cannot be loaded by more than one classloader. (http://java.sun.com/docs/books/jni/html/design.html -> 11.2.4)
So if a Geronimo application, that uses JNI, is restarted, the new classloader cannot load the library and gets java.lang.UnsatisfiedLinkError: xx (Library is already loaded in another ClassLoader) But what if you let the JNI be loaded from a different, non restartable classloader? http://cwiki.apache.org/GMOxDOC22/classloading.html "Plugins become parents of the classloader whereas jars become available directly in the classloader. " Does that mean, that a jar in the repository is within the thrown away classloader whereas a jar in a plugin is not? Then loading a DLL from a plugin would be the solution to load a native library from a non-restartable classloader, wouldn't it?
