Method Detail

resolveClass

protected Class<?> resolveClass(ObjectStreamClass osc)
                         throws IOException,
                                ClassNotFoundException

Resolves an ObjectStreamClass by delegating to Shiro's ClassUtils.forName(String) utility method, which is known to work in all ClassLoader environments.
