geotools過濾CQLException：遇到「T」

我查詢簡單的功能型架構： r:Long:index=join,*g:Point:srid=4326,di:Integer:index=join,al:Float,s:Float,b:Float,an:Float,he:Float,ve:Float,t:Float,m:Boolean,i:Boolean,ts:Long;geomesa.table.sharing='true',geomesa.indices='attr:4:3,records:2:3,z2:3:3',geomesa.table.sharing.prefix='\\u0001'geotools過濾CQLException：遇到「T」

與查詢表達式：r = 31 AND di = 5 AND BBOX(g, -38.857822, -76.111145, -74.64091, -38.61907) AND al <= 39.407307 AND s <= 1.6442835 AND b <= 83.14717 AND an <= 87.0774 AND he <= 40.89476 AND ve <= 88.761566 AND t <= 44.786507 AND m = true AND i = true.

但它拋出一個異常說Encountered "t" at line 1, column 195.

這裏是我的例外日誌詳細信息：

org.geotools.filter.text.cql2.CQLException: Encountered "t" at line 1, column 195. 
Was expecting one of: 
    <NOT> ... 
    <IDENTIFIER> ... 
    "include" ... 
    "exclude" ... 
    "(" ... 
    "[" ... 
    Parsing : r = 31 AND di = 5 AND BBOX(g, -38.857822, -76.111145, -74.64091, -38.61907) AND al <= 39.407307 AND s <= 1.6442835 AND b <= 83.14717 AND an <= 87.0774 AND he <= 40.89476 AND ve <= 88.761566 AND t <= 44.786507 AND m = true AND i = true.

我無法確定，爲什麼它是在使用名爲t的屬性查詢時拋出異常。而如果我從查詢中刪除屬性t，它會按預期工作。 t是保留鍵嗎？或者我失去了一些東西。

我剛試過這個ECQL.toFilter（「t = 44.786507」），它引發基本上相同的異常。（E）CQL解析器中可能存在一個錯誤... – GeoMesaJim
