Re: [HiveMind] Re: Tapestry exception report incomplete?

That would work. I had another idea on my way home. What if the 
constructRegistry threw an exception if there was any problem in the 
construction, that is after the registry is built? That way the 
application can decide what to do. What do you think about that?

Perhaps we should put a check in RegistryBuilder:

if (!LOG.isErrorEnabled())
 System.err.println("*** Logging not enabled for xxxx. Module parse and validation 
errors will not
be visible. ***");
In addition, an earlier version of the code had a brittle flag (that I used during 
testing). Turning
the flag on would make some errors turn into thrown exceptions. I only used it for 
testing, and
eventually discarded that and created a specialized Appended used to determine if 
certain messages
had been logged. It could be ressurected and tied to a JVM system property.

Why not just toss the thing and let the app catch it?
       

My understanding is, from a microkernel standpoint, it is 
     

not supposed
   

to crash just because one module or service had a problem, 
     

you know like 
   

the containers, they just report the problem and move on. But the 
containers have a console or a designated log file that one 
     

can take a 
   

look at, but HiveMind does not have either, that will be a 
     

problem for 
   

the uninformed, I think.
     

Hmm, not sure I agree with this --- if someone mis-configures 
a microkernel, I'd rather have it crash and tell me about it 
than sputter on and die later, pointing me elsewhere by a 
subsequently thrown exception.  I'll have to think and bring 
pursue discussion on the hivemind list.
