[dragonwell8] Set the maximum value of the G1 elastic heap during runtime.

I would like to ask a question, in G1 elastic mode, can the maximum value of the heap be changed after the JVM is started. At present, it can be seen that the maximum heap value is specified when starting the JVM, and the commit value is adjusted below this maximum value afterwards. Is there a feature in dragonwell8 that can dynamically change the maximum value of the heap like Kona JDK. Thank you very much for your answer and clarification.

It's dynamically shrinking the heap at runtime and cannot expand heap at runtime. Dragonwell JDK cannot change the maximum of heap so far. Dynamically expanding heap may affect the compressed oops and lead to performance slowdown.

Okay, thank you very much for your answer.
