    7Clone fragment #1 returns variable status with type net.sourceforge.squirrel_sql.client.update.gui.ArtifactStatus , while Clone fragment #2 returns variable index with type net.sourceforge.squirrel_sql.fw.sql.IndexInfo
    8The refactoring of the clones is infeasible, because classes and net.sourceforge.squirrel_sql.plugins.refactoring.commands.DropUniqueConstraintCommand do not have a common superclass
