During JVM startup, the class KnownOIDs is loaded. KnownOIDs has 10 anonymous
classes, which slows down the startup. This PR is to improve KnownOIDs and
eliminate unnecessary embedded classes.
Here's how to reproduce this:
public class Startup {
public static void main(String[] args) {}
}
java -verbose:class Startup
[0.665s][info][class,load] sun.security.util.KnownOIDs
[0.666s][info][class,load] sun.security.util.KnownOIDs$1
