---------------------------------
Assignee: (was: Kevin Chilton)
> More descriptive exception messages when PCJ is invalid.
> --------------------------------------------------------
>
> Key: RYA-170
> URL: https://issues.apache.org/jira/browse/RYA-170
> Project: Rya
> Issue Type: Improvement
> Reporter: Kevin Chilton
>
> When the PCJOptimizer decides a PCJ is not valid, it prints a generic message
> that does not explain why the PCJ is invalid. It would help developers debug
> their queries if the message indicated why the PCJ was invalid.
> Example of generic message:
> {code}
> Exception in thread "main" org.openrdf.query.QueryEvaluationException:
> java.lang.IllegalArgumentException: TupleExpr is an invalid PCJ.
> at
> org.openrdf.repository.sail.SailTupleQuery.evaluate(SailTupleQuery.java:67)
> at
> org.openrdf.repository.sail.SailTupleQuery.evaluate(SailTupleQuery.java:75)
> at RyaDirectExample.testAddAndDelete(RyaDirectExample.java:200)
> at RyaDirectExample.main(RyaDirectExample.java:102)
> Caused by: org.openrdf.sail.SailException:
> java.lang.IllegalArgumentException: TupleExpr is an invalid PCJ.
