Impact for JVM memory management change from Java 7 to Java 8

The memory management has been changed from Java 8 - permanent generation space has gone from heap and metaspace in native memory is introduced.

  1. Does this change impact on the JVM configuration (in this article)? (We may need to replace -XX:PermSize, -XX:MaxPermSize by -XX:MetaspaceSize, -XX:MaxMetaspaceSize. Anything else to consider?)
  2. We had done H/W sizing. The sizing sheet doesn't require to input JDK version. Is that mean this change is not impact on memory estimates in H/W sizing?
