We were testing some jdk.internal.loader.ClassLoaders changes and ran into LargeClasspathWithPkgPrefix.java jtreg test failure (java.lang.StackOverflowError), if the following constructor is used instead of URLClassPath(String, boolean) in the ClassLoaders static initializer:

public URLClassPath(URL[] urls,
                        URLStreamHandlerFactory factory,
                        @SuppressWarnings("removal") AccessControlContext acc);

[~cushon] pointed out to https://bugs.openjdk.org/browse/JDK-8308184 and suggested the fix from https://github.com/openjdk/jdk21u/pull/11/files should be applied in URLClassPath(URL[], URLStreamHandlerFactory, AccessControlContext acc) as well. I think that's the right thing to do.
