Before casting you should always check that the instance is indeed what you
think, like this:
if( needToCast instanceof IRendererFactoryTool )
IRendererFactoryTool casted = (IRendererFactoryTool) needToCast
and this saves you from nulls too, because the instanceof will be false if
needToCast is null.

A: List for discussion of JPP development and use.
Oggetto: [JPP-Devel] A question about null values...
Are you allowed to cast an object with a value of null, or does this
throw an exception?
For example, would the following statement throw an exception if the
needToCast reference was null?
IRendererFactoryTool casted = (IRendererFactoryTool) needToCast;
Thanks,
