40  * @deprecated In 3.0, the debug platform provides source lookup facilities that
41  * should be used in place of the Java source lookup support provided in 2.0.
42  * The new facilities provide a source lookup director that coordinates source
43  * lookup among a set of participants, searching a set of source containers.
44  * See the following packages: <code>org.eclipse.debug.core.sourcelookup</code>
45  * and <code>org.eclipse.debug.core.sourcelookup.containers</code>. This class
46  * has been replaced by a dialog in the debug platform -
47  * <code>org.eclipse.debug.ui.sourcelookup.SourceLookupDialog</code>.
