Yes, this is a known limitation, and currently we don't have plans to 
fix this due to technical difficulties and absence of support for this 
functionality from the native systems. Sorry about that.

Although it isn't marked as 'closed', the fix has been delivered to JDK7 
b77.

The answer to this is - yes. But there's known limitations (as with 
non-opaque lw components) which are outlined in the specification (e.g. 
see the spec for the Component class) and/or in the article that I've 
mentioned.
