    Preondition Violations
    Unmatched statement next=reader.readLine(); cannot be moved before or after the extracted code, because it has dependencies to/from statements that will be extracted

    3The refactoring of the clones is infeasible, because classes net.sourceforge.squirrel_sql.fw.dialects.DialectUtils and net.sourceforge.squirrel_sql.fw.sql.QueryTokenizer do not have a common superclass
