/**
 * Throws if adding a {@linkplain ParameterValue parameter value} to a
 * {@linkplain ParameterValueGroup group} would result in more parameters
 * than the {@linkplain ParameterDescriptor#getMaximumOccurs maximum occurence}
 * allowed. This operation may be throws during {@linkplain List#add} or
 * {@linkplain List#remove} operation on the list returned by
 * {@link ParameterValueGroup#values}.
 *
 * <P><strong>Note:</strong> This exception is of kind "{@linkplain IllegalStateException illegal
 * state}" rather than "{@linkplain IllegalArgumentException illegal argument}" because it is
 * not caused by a bad argument; it is rather a consequence of an {@linkplain ParameterValueGroup
 * parameter value group} being "full".</P>
