This is the fifth in a series of fixes for JEP 232 (Improve
Secure Application Performance) [1].

bug: https://bugs.openjdk.java.net/browse/JDK-6826789
This fix changes the keys used in the ProtectionDomain cache in
SecureClassLoader from URLs to Strings. The URL.hashCode method can
trigger a potentially expensive name service lookup. The String form of
the URL avoids that lookup, resulting in a big performance improvement.
Thanks,
