How to Set JVM Proxy Setting Without Touching the Code

-X 参数

On the basis of how we specify JVM option it can be divided into two parts, JVM Options which starts with –X and those which starts with -XX:

  1. JVM Options that begin with -X are non-standard (thy are not guaranteed to be supported on all JVM implementations), and are subject to change without notice in subsequent releases of the JDK.
  2. JVM Options or parameters which are specified with -XX are not stable and are not recommended for casual use. These options are subject to change without notice also.
