In https://bugs.openjdk.org/browse/JDK-8328278, you state:

> But the Serial GC computes tenuring threshold and prints new age table both after per GC. It causes the method `AgeTable::print_on` prints the wrong tenuring threshold.

Can you provide examples on how it "prints the wrong tenuring threshold" to illustrate the bug you had in mind that this is attempting to fix?
