Body:
I especially don't like how JDK 1.4 dumps out the chained exception's stacks. I
prefer what Tapestry does, which makes use of ExceptionAnalyzer to do the same
thing. I expect to move that code from Tapestry to HiveMind and (because
HiveMind is for JDK 1.4) make it work with the improved Exception APIs.

Here is an overview of the issue:
---------------------------------------------------------------------
Key: HIVEMIND-4
Summary: Enhance logging of exceptions when setting a service property to a
contribution
Type: Improvement
Status: In Progress
Priority: Major
Project: HiveMind
Components:
framework
Versions:
1.0
Assignee: Howard M. Lewis Ship
Reporter: Steve Gibson
Created: Mon, 7 Jun 2004 10:17 AM
Updated: Thu, 10 Jun 2004 3:54 AM
Environment: hivemind-1.0.beta-1-snapshot.jar
Description:
I am guessing the source of the exception for this, so this may be a little
vague.
If an exception is thrown due to a bug in the schema definition or a
contribution to a configuration point, when a service using the affected
configuration point is instantiated, a message of limited usefulness is logged
of the form:
ERROR: <module-id>.<service-id> - Unable to update property <property-name> of
object <service-impl-class.toString()> (at <module-descriptor-url>, line <line
number of set-configuration>): null
To me, that suggests I am getting a NullPointerException somewhere, as I dig
through the source and find in PropertyAdaptor:
try
{
_writeMethod.invoke(target, new Object[] { value });
}
catch (Exception ex)
{
throw new ApplicationRuntimeException(
UtilMessages.writeFailure(_propertyName, target, location, ex),
target,
HiveMind.getLocation(location),
ex);
}
with UtilMessages.writeFailure containing:
return HiveMind.format(
"PropertyAdaptor.write-failure",
new Object[] {
propertyName,
target,
HiveMind.getLocationString(location),
cause.getMessage()});
With a NullPointerException, the cause is null, so perhaps a better approach
would be:
cause.getMessage()!=null?cause.getMessage():cause
I will attach my test code.
I will also investigate the chain of the ApplicationRuntimeException, though
its trace is not being logged.
