when mH2i.getSerializerFactory().getClassLoader() is null , the NPE exception will occur
public <T> T readObject(Class<T> cls, Type type) throws IOException, ClassNotFoundException {
if (!mH2i.getSerializerFactory().getClassLoader().equals(Thread.currentThread().getContextClassLoader())) {
mH2i.setSerializerFactory(hessian2FactoryManager.getSerializerFactory(Thread.currentThread().getContextClassLoader()));
}
return readObject(cls);
