Groovy闭包和带有功能参数的重载方法

我写了一个小片段,显示了一个模棱两可的行为：

import java.util.function.BiConsumer
import java.util.function.Consumer

class Test {

    static void main(String... args) {
        execute({ x -> println("Consumer") })
        execute({ x,y -> println("BiConsumer") })
    }

    static void execute(Consumer<Integer> c) {
        c.accept(100)
    }

    static void execute(BiConsumer<Integer,Integer> c) {
        c.accept(1,2)
    }
}

输出(2.4.9 groovy)：

Exception in thread "main" groovy.lang.GroovyRuntimeException: Ambiguous method overloading for method Test#execute.
Cannot resolve which method to invoke for [class Test$_main_closure1] due to overlapping prototypes between:
    [interface java.util.function.BiConsumer]
    [interface java.util.function.Consumer]

但它适用于java-lambdas,我不明白如何在这种情况下使用groovy-closures.
