Description

STC Error when calling a method with an argument of null when the parameter is an array

Null parameter with array argument
import groovy.transform.*

@TypeChecked 
class Foo {
    def say() {
        methodWithArrayParam(null) // STC Error
    }
    def methodWithArrayParam(String[] s) {
        
    }
}

Other cases tested too:

Simple method call with null argument
class Foo {
    def say() {
        methodWithArrayParam(null)
    }

    def methodWithArrayParam(Date date) {

    }
}
Multiple parameters where one of them is null
class Foo {
    def say() {
        methodWithArrayParam(null, new Date())
    }
    def methodWithArrayParam(Date date1, Date date2) {

    }
}
Ambiguous method call due to null parameters
class Foo {
    def say() {
        methodWithArrayParam(null, new Date())
    }
    def methodWithArrayParam(Date date1, Date date2) {

    }
    def methodWithArrayParam(String o, Date date2) {

    }
}
Disambiguated method call
class Foo {
    def say() {
        methodWithArrayParam((Date)null, new Date())
    }
    def methodWithArrayParam(Date date1, Date date2) {

    }
    def methodWithArrayParam(String o, Date date2) {

    }
}
