Issue #2666: Unexpected query token - AS

We have an issue with following query:

SELECT DISTINCT instance, instanceEntryArtifactSet, artifact
FROM     com.btc.ep.engine.bl.internal.dmos.EngineInstanceImpl AS instance    
JOIN instance.artifacts AS instanceEntryArtifactSet ,     com.btc.ep.engine.bl.internal.dmos.ArtifactImpl AS artifact    
LEFT JOIN artifact.activatedGoals AS artifactActivatedGoals    
LEFT JOIN artifact.activatedAssumptions AS artifactActivatedAssumptions    
LEFT JOIN artifact.activatedCalibrations AS artifactActivatedCalibrations
WHERE        (    artifactActivatedGoals MEMBER OF ?1          
OR artifactActivatedAssumptions MEMBER OF ?1          
OR artifactActivatedCalibrations MEMBER OF ?1        )   
AND artifact MEMBER OF instanceEntryArtifactSet.artifacts

Caused by: com.objectdb.o.UserException: Unexpected query token 'instance.artifacts AS instanceEntryArtifactSet'

Thank you for this report. It seems as a regression bug in version 2.8.5 due to fixing another issue with using AS in queries. Please try build 2.8.5_05, which hopefully should solve this issue.

The patch solves the issue.

Thank you very much.
