All -
I'm trying to reproduce a somewhat esoteric problem encountered on a
specific JVM version and JIT behavior around VariableNotBoundException. It
was encountered in a production system, and is definitely the JVM
misbehaving, but I'm trying to reproduce this situation in a sandbox
environment.
One thing that I'm struggling with (due to not having a deep understanding
of Jena ARQ source) is what circumstances does it take for a
VariableNotBoundException to be thrown
by com.hp.hpl.jena.sparql.expr.ExprVar. I've been attempting to craft a
query case that may cause this, but so far have not been successful.
Can anyone suggest a query combination or dataset configuration that would
cultivate this flow?
Thanks!
Any expression with a variable used no where else will do it.
FILTER(?whatever)
It will (should) be caught and handled in FILTER, AS and other places an
expression occurs so it should not get out. But.
