in 5.6.4 the last PUT statement fails, although it is equivalent to the previous insertions

DELETE model_range_index

PUT model_range_index { "mappings": { "my_type": { "properties": { "my_int": { "type": "integer" }, "my_int_range": { "type": "integer_range" } } } } }

PUT model_range_index/my_type/1 { "my_int": 7 }

PUT model_range_index/my_type/2 { "my_int": 7, "my_int_range": [] }

PUT model_range_index/my_type/3 { "my_int": 7, "my_int_range": null }

This is the error response:
