Geomesa accumulo存储几何的空点

Question

我正在使用geomesa中的Point几何类型，用于特征类型中的强经度细节。在存储新功能时的用例中，我没有lat-long的值，所以我尝试为createPoint函数发送null对象，但库'jts‘在处理空几何类型时抛出异常。Here是源代码。通过查看jts库的实现，似乎很难在geomesa Point中存储null。我可以尝试的可能性是什么？以下是我的代码的快照：

sf.setAttribute(Attributes.GEOMETRY.getValue(), JTSFactoryFinder.getGeometryFactory().createPoint((Coordinate)null/*new Coordinate(event.lat, event.lng)*/));

为异常附加日志：

java.lang.IllegalStateException: getX called on empty Point

GeoMesa是一个空间/时空数据库系统。因此，在没有几何图形的情况下存储数据并不是主要用例。GeoMesa中的许多索引都假定有效的经纬度点。
