My request has a Map and put a Class[] params in this map , and I put a long
class in the params.
I find exception is in the code ByteBuffer.getObject:
String className = readUTF();
Class<?> clazz = Class
.forName(className, true, classLoader);
return ObjectStreamClass.lookup(clazz);
when className is long ,Class.forName throws exception:
