Alexander Kriegisch updated GROOVY-10450:
-----------------------------------------
Description:
The issue was first discovered by a Spock user in
[Spock-1412|https://github.com/spockframework/spock/issues/1412].
Under Groovy 3.0.9, the following code works on JREs 8-15, but starts failing
on 16+, possibly due to [JEP 396 (Strongly Encapsulate JDK Internals by
Default)|https://openjdk.java.net/jeps/396]:
{code:groovy}
import java.util.function.BiPredicate
class CombineBiPredicatesAndClosures {
static void main(String[] args) {
println "Java version: ${System.properties['java.version']}"
// Old-school anonymous class instead of closure or lambda
/*
BiPredicate<String, Integer> bi = new BiPredicate<String, Integer>() {
@Override
boolean test(String domain, Integer score) {
return domain.equalsIgnoreCase("google.com")
}
}
*/
// Lambda syntax only works in Groovy 3+
//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 logicalNot = bi.negate()
assert logicalNot.test("acme.org", 11)
assert !logicalNot.test("google.com", 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)
}
}
{code}
Running the program yields something like:

When running the same program on Groovy 4.0.0-rc-2, there are no problems on
JDK 16+. Using the commented-out anonymous class instead of either a lambda or
closure also works around the problem on Groovy 3.
Could you please fix this for the next 3.0.x version? Thank you.
