Closing as the issue is with Groovy.

Hm, I see that Groovy seems to permit chaining of bi-predicates and/or closures using bitwise logical operators. As a Groovy non-expert, I had no idea that was possible. I also did not find any relevant documentation about this. Maybe I searched for the wrong keywords.

Anyway, without Spock, this works in JDK <16, while it fails the way you described above in JDK 16+. This holds true independent of whether we use Java lambda or Groovy closure syntax.

package org.acme

import java.util.function.BiPredicate

class CombineBiPredicatesAndClosures {
  static void main(String[] args) {
    println System.properties["java.version"]

    // Lambda syntax only works in Groovy 3.0
    // BiPredicate<String, Integer> bi = (domain, score) -> domain.equalsIgnoreCase("google.com")
    // def bi2 = (domain, score) -> score == 11

    // Closure syntax works in Groovy 2.5, too
    BiPredicate<String, Integer> bi = { domain, score -> domain.equalsIgnoreCase("google.com") }
    def bi2 = { domain, score -> score == 11 }

    def logicalOr = bi | bi2
    assert logicalOr.test("google.com", 11)
    assert logicalOr.test("google.com", 0)
    assert logicalOr.test("x", 11)
    assert !logicalOr.test("x", 0)

    def logicalAnd = bi & bi2
    assert logicalAnd.test("google.com", 11)
    assert !logicalAnd.test("google.com", 0)
    assert !logicalAnd.test("x", 11)
    assert !logicalAnd.test("x", 0)
  }
}

Try it in the Groovy Web Console, where it always works, because GWC runs on JRE 11.

So we are dealing with a Groovy issue, as it seems. As usual, @leonard84 is right in such things.
