Problem

When building the method description text for the arity mismatch exception in the NewExpr constructor added in 1.12.0-alpha7, the class name is passed instead of “new” as the constructor’s name.

Symptom

The constructor arity mismatch error is using the “Invocation of method java.lang.String" wording, should be constructor:

I think this is because it’s looking for “new” but this is the actual constructor name by this point.

Approaches

• Pass the string “new” to the methodDescription method when the method is a Constructor instance in the checkMethodArity method – NO that method should not know about “new”

• Make methodNamesConstructor smarter about identifying that a class name and method name being equal signals a constructor – NO that opens up new syntax

• Make methodDescription smarter about identifying that a class name and method name being equal signals a constructor
