Key: HIVEMIND-19
Summary: More descriptive exception reporting
Type: Improvement
Status: Closed

Description:
I believe Registry.getService should throw more descriptive exceptions in the
sprit of Class.forName.
Currently Registry.getService throws ApplicationRuntimeException and the user
needs to interrogate the message to see what happend.
It is desirable for Registry.getService to throw more descriptive exceptions
when well defined events occur.
- ServiceNotFoundException - there was no metadata defined for that service-id.
- ServiceInstantiationException - there was syntactically valid metadata for
the requested service-id but the implementation could not be instantiated for
some reason.
- ServiceTimeoutException - there was a pooled resource timeout for the
requested service-id.
The reason such exceptions are valuable in my situation is that I have legacy
services that may or may not also be defined in Hivemind. I wish to check
Hivemind first and failing that then try the legacy lookup. Differentiating
between not found, not instantiated, timed out is extremely helpful in this
case.
