When try to index **{"ets":1.56380271344E12}** this event into elastic search it's throwing an `illegal_argument_exception`  
**Spec:**

Log stash Version:2.3.4  
Elastic search Version: 2.4.5

**Input events:**

Event1: {"ets":1.56380271344E12} // **Fails to index**

Event2 {"ets":1.563803028911E12} // **Works fine**

**ES-Mapping :**

"ets": {  
"format": "date\_hour\_minute\_second\_millis||epoch\_millis",  
"type": "date"  
}

**Error:**

`"error"=>{"type"=>"mapper_parsing_exception", "reason"=>"failed to parse [ets]", "caused_by"=>{"type"=>"illegal_argument_exception", "reason"=>"Invalid format: \"1.56380271344E+12\" is malformed at \".56380271344E+12\""}}}}, :level=>:warn}`

Did anybody faced this issue? Can you please help me how to resolve this or any workaround?
