GetInterfaces test in TestClassUtil.java appears to be checking interfaces of Java builtins?

[josh-thisisbud]

I just want to prefix all of this with I know very little about Java, and I'm only building this tool because I'd like to use it to benchmark, having pre-compiled versions would be really handy.

I modified the test to:

    /**
     * GetInterfaces
     */
    @Test
    public void testGetInterfaces() {
        Class<?>[] expected = {
                Serializable.class,
                Cloneable.class,
                Iterable.class,
                Collection.class,
                List.class,
                RandomAccess.class,
        };
        Collection<Class<?>> results = ClassUtil.getInterfaces(target_class);
        // System.err.println(target_class + " => " + results);
        assert (!results.isEmpty());
        assertEquals(String.format("Target class was %s", target_class), expected.length, results.size());

        for (Class<?> e : expected) {
            assert (results.contains(e));
        } // FOR
    }

This resulted in output of

hi @josh-thisisbud, did you solve this issue? I have the same error when building benchbase with the Microsoft build of openjdk 21 without modifying anything.

[josh-thisisbud]

I removed the problematic test and compiled that way

Thank you for the quick response! Same here. Not familiar with Java and ended up commenting out the test.

FYI, this should be fixed now. Let us know how it goes. Thanks for reporting!
