------------------------------------

             Summary: StackOverflowError on Java 16+ for override method that delegates to super
                 Key: GROOVY-10302
                 URL: https://issues.apache.org/jira/browse/GROOVY-10302
             Project: Groovy
          Issue Type: Bug
          Components: jdk conflict
    Affects Versions: 4.0.0-beta-1
            Reporter: Eric Milles


Consider the following:
{code:groovy}
void test() {
    def list = []

    def loader = new GroovyClassLoader() {
        @Override
        protected Class<?> findClass(String name) throws ClassNotFoundException {
            list.add(name); super.findClass(name)
        }
    }

    Class result = loader.findClass('foo.bar.Baz')
}
{code}

When executed on Java 16+ it produces a StackOverflowError when resolving "super.findClass(name)".
