Hi Sergey,

I don't believe so. While LWAWT toolkit uses Swing components 
internally, these internal components never use a real component from 
the actual components hierarchy as their parent. Invalidating the 
internal components can't cause the actual components to be invalidated.

Also, according to your comment in the bug report, you couldn't 
reproduce this issue on Mac.

So, I don't think this is a problem for any other toolkit or component.

best regards,
