Bug 4121 JarExporter causes out of Sync (1GILQD5)
PA (8/17/01 2:03:29 PM) if you export a directory (project) and place the exported jar in the same directory (project) then you will get an out of sync message when you overwrite the exported jar-file the 2nd time. -> maybe the exported jar file should not include itself ? NOTES:
org.eclipse.jdt.ui/ui/org/eclipse/jdt/internal/ui/jarpackager/JarPackageWizardPage.java
* Creates the export type controls.
	 *
	 * @param parent the parent control
	 */
	protected void createExportTypeGroup(Composite parent) {		
		Composite optionsGroup= new Composite(parent, SWT.NONE);
		GridLayout optionsLayout= new GridLayout();
		optionsLayout.marginHeight= 0;
		optionsGroup.setLayout(optionsLayout);
		fExportClassFilesCheckbox= new Button(optionsGroup, SWT.CHECK | SWT.LEFT);
		fExportClassFilesCheckbox.setText(JarPackagerMessages.getString("JarPackageWizardPage.exportClassFiles.text")); 
		fExportClassFilesCheckbox.addListener(SWT.Selection, this);
		fExportJavaFilesCheckbox= new Button(optionsGroup, SWT.CHECK | SWT.LEFT);
		fExportJavaFilesCheckbox.setText(JarPackagerMessages.getString("JarPackageWizardPage.exportJavaFiles.text"));
