        Description


        If a malformed policy file is encountered when running with a custom system class loader then it leads to a recursive initialization issue.

        To demonstrate then see the attached test case and run it with:

        java -Djava.system.class.loader=MyClassLoader -Djava.security.manager -Djava.security.policy=java.policy Main

        The stack trace with jdk-9+140 is below. It's possible to change SL to not use getSystemClassLoader but that just moves the problem to ResourceBundle. The stack trace with JDK 8 is different but amounts to the same thing.
