No, it isn't that complicated.
Take another class sun.security.jca.ProviderList$1 for example:
6-b54: 1151354171352296389L
6-b55: -8369942687198303343L (6219964)
6u3-latest: -8369942687198303343L
6u4-latest: 1151354171352296389L (6520152)
So the times are connect. sun.security.pkcs11.P11TlsPrfGenerator$1 is a
JCE class which is inside the ext/sunpkcs11.jar. Most likely that jar
was only compiled using the new javac from 6u11.

Interesting - 6520152 was fixed in 6u4, so it would appear that this got
turned on again at some stage and then off again in 6u11. Though I don't
see a bug fix in 6u11 that would cover this.

I think that's a javac issue. The inner class has an attribute which
describes the access flags that the VM should report and that changed
in _11. Here it is in _10.
Attr(#25) { // InnerClasses
[] { // InnerClasses
#4 #0 #0 24;
}
} // end InnerClasses
and here's _11:
Attr(#25) { // InnerClasses
[] { // InnerClasses
#4 #0 #0 8;
}
} // end InnerClasses

I find out the reason:
Since 6u11, a final inner class is *not* final anymore.
$ cat A4.java
import java.lang.reflect.Modifier;
public class A4 {
public static void main(String[] args) throws Exception {
Class c = Class.forName(args[0]);
System.out.println(c.getModifiers() & Modifier.FINAL);
}
}
$ java A4 java.lang.String
16
$ java A4 'sun.security.pkcs11.P11TlsPrfGenerator$1'
0
getModifiers() is a native method, and calls JVM_GetClassModifiers.
Is this an intended change?
FYI, the class is defined as
private static final SecretKey NULL_KEY = new SecretKey() {
....
in
http://hg.openjdk.java.net/jdk8/tl/jdk/file/809e8db0c142/src/share/classes/sun/security/pkcs11/P11TlsPrfGenerator.java,
line 100.
