  org.pentaho.reporting.engine.classic.core.modules.gui.commonswing.action.DowngradeActionMap

public class DowngradeActionMap
extends Object

An actionmap, which is JDK 1.2.2 compatible.

This implementation does not implement the ActionMap interface of JDK 1.3 or higher to maintain the compatibility with JDK 1.2 which does not know this interface.

The usage is still the same.
