Description
See issue #1031.
Latest version of spec, section 10.10.1 replaces errors with warnings in cases where the class or the constructor is undeclared. Motivation is similar to other cases: do not impose workflow - just warn and make it a dynamic error.
"Let e be a new expression of the form new T.id(a1, .., an, xn+1: an+1, …, xn+k: an+k) or the form new T(a1, .., an, xn+1: an+1, …, xn+k: an+k). It is a static warning if T is not a class or interface accessible in the current scope, optionally followed by type arguments.
If e is of the form new T.id(a1, .., an, xn+1: an+1, …, xn+k: an+k) it is a static warning if T.id is not the name of a constructor declared by the type T. If e of the form new T(a1, .., an, xn+1: an+1, …, xn+k: an+k) it is a static warning if the type T does not declare a constructor with the same name as the declaration of T.
"
Consequently, it is a dynamic error to call such an undefined constructor:
"Evaluation of e proceeds as follows:
If T is not a class or interface accessible in the current scope, a dynamic error occurs. Otherwise, if q is not defined, a NoSuchMethodError is thrown. Otherwise, if q is a generative constructor (regardless of whether q is redirecting or not), then: ..."
