What happened?

Description

In objmodel, a double value e.g. 1.0 is encoded as 1 in the resulting json, causes it to be dynamically mapped in Elasticsearch as a long instead of a double / float.

Steps to Reproduce

1. Send 1.0 to Elasticsearch to a field with dynamic mapping
2. Query it back
3. Check resulting mapping

Expected Result

Getting 1.0 back, mapped as double.

Actual Result

Get 1 back, mapped as long

Collector version
