LoginContext.login() performs slow in comparison with OpenJDK8.
ServiceLoader lookup ( method ServiceLoader.load() ) performs many times repeatedly, each time when application calls LoginContext.login().
On multi-threading application, this leads to having a lot of threads waiting for synchronized code URLClassPath.getLoader().
