Description

The following code (from Map#each documentation in the Groovy JDK) fails under static compilation:

import groovy.transform.CompileStatic

@CompileStatic def test() {
    def result = ""
    [a:1, b:3].each { key, value -> result += "$key$value" }
    assert result == "a1b3"
}
test()

with the message:

Caught: groovy.lang.MissingMethodException: No signature of method: mapeach$_test_closure1.doCall() is applicable for argument types: (java.util.LinkedHashMap$Entry) values: [a=1]
Possible solutions: doCall(java.lang.Object, java.lang.Object), findAll(), findAll(), isCase(java.lang.Object), isCase(java.lang.Object)
