Knox rewrites numbers in JSON to engineering notation

Converting to engineering notation occurs only when buffering has been configured in the rewrite rules. It's related to usage of BigDecimal.stripTrailingZeros() in the com.fasterxml.jackson.databind.node.JsonNodeFactory.numberNode(BigDecimal v) by default.

For example, original JSON

{
	"apps":{
		"app":[
			{
				"id":"one",
				"progress":100.0,
				"startedTime":1399975176760
			}
		]
	}
}

Rewritten JSON

{
	"apps":{
		"app":[
			{
				"id":"one",
				"progress":1E+2,
				"startedTime":1.39997517676E+12
			}
		]
	}
}
