Please review this fix to a regression introduced in JDK 9. An
application run with a SecurityManager and using a JDK that is accessed
over the network using a UNC path fails to startup and throws an
InternalError.
The fix is to load default.policy as a regular File rather than a URL
(URLs are only necessary for policy files configured in the
java.security file). No regression test because it involves a manual
setup (noreg-hard).
