docs: Get a process for a JVM. The class path for the JVM is computed
  based on the class loaders for the main class.
  @param mainClass Fully qualified class name of the main class
  @param args Additional command line parameters
  @return ProcessBuilder that has not been started.
  @deprecated This acquires the mainClass class by using the
  {@link Thread#getContextClassLoader() thread context class loader}
  or this class's class loader. Depending on where mainClass
  was loaded from neither of these may work.
