/**
* Constructs an {@code OpenMBeanParameterInfoSupport} instance, which describes the parameter

* {@code name}, {@code openType}, {@code description}, and {@code descriptor}.
*
* <p>The {@code descriptor} can contain entries that will define the values returned by certain
* methods of this class, as explained in the {@link <a href="package-summary.html#constraints">
* package description</a>}.
*
* @param name cannot be a null or empty string.
* @param description cannot be a null or empty string.
* @param openType cannot be null.
* @param descriptor The descriptor for the parameter. This may be null which is equivalent to an
* empty descriptor.
* @throws IllegalArgumentException if {@code name} or {@code description} are null or empty
* string, or {@code openType} is null, or the descriptor entries are invalid as described in
* the {@link <a href="package-summary.html#constraints">package description</a>}.
