Summary: 0005185: Marshalling (php->enum) of null for enums fails
Description: When testing quercus for internal systems I noticed, that some aspects of our internal api could not be used, as the system failed to correctly marshal null values for enums.

---------- Minimal example: -----------

===== File: Test.java ======
public class Test {
    public void testEnum(TestEnum x) {
        System.out.println(x);
    }
}

===== File: TestEnum.java ======
public enum TestEnum { A, B }

===== File: test.php =====
<?

import Test;
import TestEnum;

$a = new Test();

$a->testEnum( null );
$a->testEnum( "A" );
$a->testEnum( TestEnum::B );

===== Invokation ======
java -cp lib/resin.jar:. com.caucho.quercus.CliQuercus test.php

===== Output =====
Exception in thread "main" java.lang.IllegalArgumentException: No enum constant TestEnum.

===== Expected Output =====
null
A
B
