------------------------------------
Summary: STC method reference return type checking
Key: GROOVY-10858
URL: https://issues.apache.org/jira/browse/GROOVY-10858
Project: Groovy
Issue Type: Bug
Components: Static Type Checker
Affects Versions: 4.0.6, 3.0.13
Reporter: Eric Milles
Assignee: Eric Milles
Consider the following:
{code:groovy}
@groovy.transform.CompileStatic
void test() {
java.util.function.Function<Object,Number> f = Object::toString
print(f.apply('xxx'))
}
{code}
This code compiles and prints the string instead of a compile-time error
indicating that String is not compatible with Number.
