Bug in logic for decoding anything other than MapClaims

[smcallis]

jwt-go/parser.go

Line 131 in dc14462

err = dec.Decode(&claims)

Since this function takes claims as Claims, if you pass anything other than MapClaims{}, you'll get an unmarshalling error:
Error verifying token: json: cannot unmarshal object into Go value of type jwt.Claims

#457 this project is unmaintained, I suggest using an alternative

We also encountered the same issue.
This should be the code snippet explaining why this wont work: https://play.golang.org/p/Tf-JYrfmbXO

ah, if you use &MapClaims{} instead of MapClaims{} it will work. See https://stackoverflow.com/questions/50564341/pointer-to-an-interface-vs-interface-holding-a-pointer-when-unmarshaling-json for more explanations
