Memory leak in css code

[GoogleCodeExporter]

What steps will reproduce the problem?
1. create new components
2. destroy them
3. check memory usage

Problem probably in getRelevantStyles in CSSStyleManager

public List<CSSStyleHierarchy> getRelevantStyles(MTComponent c) {
        if (!components.contains(c) && c instanceof CSSStylableComponent){ 
            //here exactly
            components.add((CSSStylableComponent)c);
        }

they dont get removed

if you add:

/**
 * Unregister component.
 *
 * @param c the c
 */
public void unregisterComponent(CSSStylableComponent c) {
    components.remove(c);
} 

to the CSSStyleManager
and 

@Override
public void destroy() {
    this.mtApp.getCssStyleManager().unregisterComponent(this);
    super.destroy();
}

to the MTCSSStylableShape the problem should be solved
