[picocontainer-dev] Exception as message passing in ConstantParameter

ConstantParameter has a method like :-

>     public boolean isResolvable(PicoContainer container,  
> ComponentAdapter<?> adapter, Type expectedType,
>                                                NameBinding  
> expectedNameBinding, boolean useNames, Annotation binding) {
>         if (expectedType instanceof Class) {
>             try {
>                 verify(container, adapter, expectedType,  
> expectedNameBinding, useNames, binding);
>                 return true;
>             } catch(final PicoCompositionException e) {
>                 return false;
>             }
>         }
>         return false;
>     }

It feels a bit icky. In our larger test suite for Pico, the catch is  
called some 26 times.  I could not say for sure whether its a marginal  
or a core code-path.  Maybe not now, but verify(..) could return  
something more sophisticated than void.
