/* @test
* @bug 5015331
* @summary PreferredClassLoader should have a constructor that has a
* URLStreamHandlerFactory, like URLClassLoader does. If specified,
* the URLStreamHandlerFactory should be passed to the superclass
* constructor, and it should be used to create a URLStreamHandler for
* "jar:" URLs that get used when the loader creates such URLs for
* retrieving the preferred list and resources from codebase path
* elements that do not end with "/".
*
* @build TestURLStreamHandlerFactory Foo
* @run main/othervm/policy=security.policy TestURLStreamHandlerFactory
