* SpringSource Tool Suite Team - This class was copied from Eclipse 3.4 for use in 3.3-based distributions. Necessary

* NewJavaProjectWizardConstants. All working set functionality has been commented out in order to retain compatibility
* between 3.3 and 3.4
*
* @deprecated As of release 2.0.0, STS only supports Eclipse 3.4 and above. Use {@link NewJavaProjectWizardPageOne}
* instead. ----------------------------------------------------------------------------- The first page of
* the New Java Project wizard. This page is typically used in combination with
* {@link NewJavaProjectWizardPageTwoCOPY}. Clients can extend this page to modify the UI: Add, remove or
* reorder sections.
* <p>
* Clients may instantiate or subclass.
* </p>
* <p>
* <strong>EXPERIMENTAL</strong> This class or interface has been added as part of a work in progress. This
