On the isVarArgs method of Method after java dynamic proxy

problem description

The class returned after the

java dynamic proxy returns true when calling the isVarArgs method that contains an indefinite length parameter Method instance in the class without going through the proxy and cglib proxy. So I"d like to ask, is this the question of java dynamic agents?

the environmental background of the problems and what methods you have tried

Today, I encountered a problem when using activiti. When I showed that the proxy mode of the specified transaction was Java dynamic proxy, the task listener configured in activiti threw an exception when calling the method of bean in the spring container and could not find the method. After searching for a period of time, I found that this method was used in activiti to determine whether the method in the expression was used correctly, as follows:

give me an explanation of what I want to know. I haven"t found out a lot of things. If I don"t know, I"ll take it as a record.
