For Java 11 and above. The Xmx value is 25% of the available memory with a maximum of 25 GB. However, where there is 2 GB or less of physical memory, the value set is 50% of available memory with a minimum value of 16 MB and a maximum value of 512 MB. For Java 8 The Xmx value is half the available memory with a minimum of 16 MB and a maximum of 512 MB. Remove fixed young generation heap space of JVM instance For Java 11 and above.
