I am transforming > OpBGP into OpQuadBlock (not OpQuadPattern). > Most queries work fine except when using one of the following: > * MINUS > * FILTER EXISTS > * FILTER NOT EXISTS > I tracked the issue down to this visitor: > org.apache.jena.sparql.algebra.OpVarsPattern. > An override for visit(OpQuadBlock) is missing. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
