    Description

      jlf_tuplejoblist.cpp::spanningTreeCheck() has a loose check that fails when ON clause contains references to 2 of 3 joined tables. One could reproduce the problem using the SQL statements from the attached file.
      For this particular situation nodeSet.size() = 3 and pathSet.size() = 6 in the end of the spanningTreeCheck(), that fails the spanning tree check.
