Object proxyFactory = ClassUtils.tryToInstantiateClassForName("javassist.util.proxy.ProxyFactory");
Method setSuperclassMethod = proxyFactory.getClass().getDeclaredMethod("setSuperclass", Class.class);
proxyFactory is null when javassist is not on classpath.
Also note that tests for partial beans do not bundle javassist within the test archive which they should! Otherwise those tests won't pass on a container that does not implicitly add javassist to the classpath (e.g. WildFly).
