Hi @kl0u I changed a bit of the implementation of JIRA, instead of
implement multi wrapper classes for different `State`, I introduce a
`StateInvocationHandler` which implemented `InvocationHandler` to delegate the
`clear()` method of `State` , could you please have a look at this? and please
let me know if you have any advice.---
