As a result, you may not realize any benefits from using compressed pointers with large Java heap sizes. -XX:OnError=string Sets a custom command or a series of semicolon-separated commands to run when an irrec
IANA Data 2017c JDK 8u161 contains IANA time zone data version 2017c. For more information, refer to Timezone Data Versions in the JRE Software. New Feature: Support DHE sizes up to 8192-bits and DSA sizes up to 3072-bits Enhance the JDK security providers to support 3072-bit Diffie...
int: By default, the int data type is a 32-bit signed two's complement integer, which has a minimum value of -231 and a maximum value of 231-1. In Java SE 8 and later, you can use the int data type to represent an unsigned 32-bit integer, which has a minimum value of 0 and...
Object packing functionality has been added to minimize the wasted space between data types of different sizes. This is primarily a benefit in 64-bit environments, but offers a small advantage even in 32-bit VMs. For example: public class Button { char shape; String label; int xposition; in...

Large stack sizes in a JVM with many threads may use a large amount of memory. Kryo setMaxDepth can be used to limit the maximum depth of an object graph. This can prevent malicious data from causing a stack overflow. Accepting null By default, serializers will never receive a null, ...
