Bug 47208 Generate Javadoc dialog lays out too wide [javadoc]
If one uses a custom doclet and sets the doclet class path to a long path (e.g. with many JAR files on it), the "Generate Javadoc" dialog lays out to try and fit the full doclet class path on the screen; this results in a very wide dialog.
org.eclipse.jdt.ui/ui/org/eclipse/jdt/internal/ui/javadocexport/JavadocTreeWizardPage.java
return fCustomButton.getSelection();
	}
	private void setOptionSetSettings() {
		if (!fStore.fromStandard()) {
			fCustomButton.setSelection(true);
			fDocletText.setText(fStore.getDocletPath());
			fDocletTypeText.setText(fStore.getDocletName());
			
			fDestinationText.setText(fStore.getDestination((IJavaProject) fWizard.getSelectedProjects().iterator().next()));
			fDestinationText.setEnabled(false);
			fDestinationBrowserButton.setEnabled(false);
			fDestinationLabel.setEnabled(false);
			
		} else {
			fStandardButton.setSelection(true);
			if (fWizard.getSelectedProjects().size() == 1)
				fDestinationText.setText(fStore.getDestination((IJavaProject) fWizard.getSelectedProjects().iterator().next()));
			else
				fDestinationText.setText(fStore.getDestination());
			fDocletText.setText(fStore.getDocletPath());
			fDocletTypeText.setText(fStore.getDocletName());
			fDocletText.setEnabled(false);
			fDocletLabel.setEnabled(false);
			fDocletTypeText.setEnabled(false);
			fDocletTypeLabel.setEnabled(false);
		}
		String javadocCommand = JavadocPreferencePage.getJavaDocCommand();
		fJavadocCommandText.setText(javadocCommand);
		fJavadocCommandText.setToolTipText(javadocCommand);
