The usual trick with this kind of restriction is to install a wrapper in the classpath. This delegates to the real implementation which can be hot deployed and lazily instantaniated in the application classloading context. The JVM loads the wrapper using the system classloader from the classpath. The wrapper uses the context classloader. This has always been a problem with IBM's VMs. While we're on the subject, somebody should explain to the jdk developers why Class.forName() has no notion of application context when there are multiple applications running on different threads in the same VM.
