When loading a signed jar file that is on the classpath, such as the bouncy castle signed JCE jar file, it has been observed that the value of `restrictedJarVerificationProviders` and `jarVerificationProviders` are set to `null`. This causes a NullPointerException during the loading process. This update moves the static declarations of both `restrictedJarVerificationProviders` and `jarVerificationProviders` to be prior to the method call `RestrictedSecurity.checkHashValues()` since this method call needs both of these fields to be initialized to work correctly.
