> I have the following program

> abstract class Foo {
> Foo(String x) {}
> }
> class Test {
> public static void main(String[] args) {
> Function<String, Foo> x = Foo::new;
> x.apply("d");
> }
> } {code}
> h3. Actual behavior
> The program compiles but I get the following runtime exception, because I
> call the constructor of an abstract class.
> {code:java}
> Exception in thread "main" java.lang.InstantiationException: Foo
> at java.base/jdk.internal.misc.Unsafe.allocateInstance(Native Method)
> at
> java.base/java.lang.invoke.DirectMethodHandle.allocateInstance(DirectMethodHandle.java:501)
> at
> org.codehaus.groovy.vmplugin.v8.IndyInterface.fromCache(IndyInterface.java:336)
> at Test.ctorRef$main$0(test.groovy)
> at Test.main(test.groovy:10)
> {code}
> h3. Expected behavior
> The program should have been rejected instead.
