Motivation

Reducing resource requirements and improving the process stability.

Modifications

1. Allocate JVM memory based on the container memory and percentage. By default, the direct memory equals the max percentage. So the final allocation is 40% max heap + 40% max direct memory + 20% misc.
2. Turn on GC logs
3. Turn on heapdump
