Hi,
Just running some tests in trunk and I'm seeing some exceptions without
stacktrace:
2008-02-11 00:54:23,416 WARN
[org.jboss.beans.metadata.plugins.AbstractListMetaData] Exception in
preinstantiated lookup for:
TomcatClusteringEvictionConfig.evictionRegionConfigs,
org.jboss.cache.config.ConfigurationException:
org.jboss.cache.config.ConfigurationException: timeToLiveSeconds must be
configured to a value greater than or equal to 0
....
2008-02-11 00:54:59,867 WARN
[org.jboss.beans.metadata.plugins.AbstractListMetaData] Exception in
preinstantiated lookup for:
EJB3SFSBEvictionConfig.evictionRegionConfigs,
org.jboss.cache.config.ConfigurationException:
java.lang.ClassCastException:
org.jboss.cache.eviction.NullEvictionPolicyConfig
Shouldn't AbstractTypeMetaData.preinstantiatedLookup() print the
stacktrace? That would certainly help debugging them :)
So, instead of:
catch (Throwable t)
{
log.warn("Exception in preinstantiated lookup for: " + beanName +
"."
+ propertyName + ", " + t);
}
do:
catch (Throwable t)
{
log.warn("Exception in preinstantiated lookup for: " + beanName +
"."
+ propertyName, t);
}

Don't blame your problems on the stack trace. :-)
1st one is obvious, and no stack trace would tell you more.
The 2nd needs a bit more, probably 3sec of a look at xml. ;-)

Actually not true. It's a known (to Manik and I) issue that's already
been addressed for JBC 2.1.0.CR4. But unless you know what
"preinstantiated lookup" means in the log message, the fact that the
problem occurs when the MC calls the getter method for a property before
calling the setter to inject what's been configured, it's not at all
clear why the problem occurred. Calling the getter before the setter
triggered an unintended code path; that's been fixed. That the MC would
make such a call is not intuitively obvious.
I can see not wanting to log the stack trace at WARN. Perhaps at DEBUG.
The 2nd needs a bit more, probably 3sec of a look at xml. ;-)
I'll let you know after I figure it out. May be fast since I now know
what "preinstantiated lookup" means. :-)

Your missing the point. It's not about how easily the exception can be
resolved. An Exception contains a message and a stacktrace. To log
Exception information partially is IMO a bad practice.
