* And the JDI client defines these <CODE>Field</CODE> objects:
* <PRE>

* {@link ReferenceType} for <CODE>java.util.Date</CODE> and
* <CODE>((ArrayType)(baField.type())).componentType()</CODE> is a
* {@link ByteType}.
* <P>
* Note: if the type of this field is a reference type (class,
* interface, or array) and it has not been created or loaded
* by the declaring type's class loader - that is,
* {@link TypeComponent#declaringType <CODE>declaringType()</CODE>}
* <CODE>.classLoader()</CODE>,
* then ClassNotLoadedException will be thrown.
* Also, a reference type may have been loaded but not yet prepared,
* in which case the type will be returned
* but attempts to perform some operations on the returned type
* (e.g. {@link ReferenceType#fields() fields()}) will throw
* a {@link ClassNotPreparedException}.
* Use {@link ReferenceType#isPrepared()} to determine if
* a reference type is prepared.
*
* @see Type
* @return the {@link Type} of this field.
* @throws ClassNotLoadedException if the type has not yet been loaded
