> When using an _UDAF_ in a _VDB_, the required *JAVA_CLASS* and *JAVA_METHOD* are specified in the _VDB_.
> When for some reason the _JAVA_CLASS_ or _JAVA_METHOD_ do not exist in the library, the message from the system is quite imperceptible.
> In the following log excerpt, _GlobalTitleRangeCheck_ class does not exist in the _jar_ _rangecreator_. The model name that is defining the _VIRTUAL FUNCTION_ is _RangeGroupConcat_. The _VDB_ name is _CountryServiceListVDB_.
> {panel:title=Log excerpt}
> DEBUG [org.teiid.RUNTIME] (Worker53_async-teiid-threads203)  TEIID50104 VDB CountryServiceListVDB.1 model "RangeGroupConcat" Using translator null and connection null to load metadata.

> INFO  [org.teiid.RUNTIME] (Worker53_async-teiid-threads203)  TEIID40073 The metadata for the VDB CountryServiceListVDB.1 is loaded, however it is not valid. Check models for errors. Correct the metadata and re-deploy.
> INFO  [org.teiid.RUNTIME.VDBLifeCycleListener] (Worker53_async-teiid-threads203)  TEIID40003 VDB CountryServiceListVDB.1 is set to FAILED
> {panel}
> As observed from the log excerpt, the only possible hint to know what the problem is with the _FAILED_ deploy might be:
> _model "RangeGroupConcat" Using translator null and connection null to load metadata._
> But this is a normal logging message that doesn't have nothing to do with the real problem.
> When putting the entire system logging _ALL_ levels, then is easy to see what the problem is:
> {panel:title=Log excerpt}
> DEBUG [org.teiid.RUNTIME] (Worker52_async-teiid-threads202)  TEIID50104 VDB CountryServiceListVDB.1 model "RangeGroupConcat" Using translator null and connection null to load metadata.

> Here it is observable what the real problem is:
> _No local specification found for class com.truphone.teiid.udaf.GlobalTitleRangeCheck in Module "mnom.rangecreator:main"_
> So, to avoid unnecessarily losing time to investigate what the problem is, the message that is currently in *TRACE* level should be in, at least, *INFO* level.
