Holger Knublauch created JENA-500:
-------------------------------------
Summary: SPARQL optimizer does not consider pre-bound variables,
creates wrong query
Key: JENA-500
URL: https://issues.apache.org/jira/browse/JENA-500
Project: Apache Jena
Issue Type: Bug
Components: Optimizer
Affects Versions: Jena 2.10.2
Reporter: Holger Knublauch
There is a regression bug somewhere between 2.7.2 and 2.10.2.
See test case which works green in the old version but fails on the
latest snapshot. I believe the cause is that
TransformFilterImplicitJoin.testSpecialCaseUnused() incorrectly assumes
it can ignore the whole query if it encounters unbound variables.
However, in my case the variables do have values, coming from the
initial binding of the QueryExecution.
