      explicitly use 

      Bean( map.containsKey("x") ) // vs. map.containsValue("x")

      or

      Bean( map.values() contains "x" ) // vs map.keySet() contains "x"
      Show
      explicitly use Bean( map.containsKey( "x" ) ) // vs. map.containsValue( "x" ) or Bean( map.values() contains "x" ) // vs map.keySet() contains "x"

    Description

      In a rule

      Bean( map contains "x" ) // assuming "map" is a property of type Map

      "contains" is arbitrarily interpreted as "containsKey"
      The constrain will then fail after being jitted

      The documentation explicitly states that "contains" applies to collections
