Ok, my example was not complete :(
In my case the parent CM catches the NPE of the component and
rethrows it as a ComponentException. So if I change the above
line to catch only ComponentExceptions it's not better.
What about changing it to:
if( m_parentManager != null && m_parentManager.hasComponent( role ) )
{
return parentManager.lookup( role );
}
