-/**
- * Information about a VM option including its value and
- * where the value came from which is referred as its
- * {@link VMOption.Origin <i>origin</i>}.
- * <p>
- * Each VM option has a default value.  A VM option can
- * be set at VM creation time typically as a command line
- * argument to the launcher or an argument passed to the
- * VM created using the JNI invocation interface.
- * In addition, a VM option may be set via an environment
- * variable or a configuration file. A VM option can also
- * be set dynamically via a management interface after
- * the VM was started.
- *
- * A <tt>VMOption</tt> contains the value of a VM option
- * and the origin of that value at the time this <tt>VMOption</tt>
- * object was constructed.  The value of the VM option
- * may be changed after the <tt>VMOption</tt> object was constructed,
