Body:
Actually, this is exacerbated by the fact that, though
ApplicationRuntimeException extends RuntimeException, it does not pass on the
root cause which means you still lose the rest if the stack trace.
I don't know if this is meant for compatibility with older jvms, but it would
be nice to be able to get that trace. I modified the source of mine to pass the
root cause on to the superclass (and set getRootCause to super.getCause() and I
got a couple of extra levels of trace before it was truncated for me by the jvm
(I am guessing).
I got:

At least this gives me more to go by, though I guess I forgot to turn debug on
in ant compiles.

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: Unassigned
Priority: Major
Project: HiveMind
Components:
framework
Versions:
1.0
Assignee:
Reporter: Steve Gibson
Created: Mon, 7 Jun 2004 10:17 AM
Updated: Mon, 7 Jun 2004 11:10 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.
