> Using the log4j2 JsonLayout can result in invalid JSON. Some parsers could not parse this syntax.
>  The problem ist the attribute "nanoOfSeconds" from the timestamp:
> {code:javascript}
> {
>   "loggerFqcn": "org.apache.catalina.valves.AccessLogValve",
>   "instant": {
>     "epochSecond": 1578393313,
>     "nanoOfSecond": 008000
>   },
>   "clientIp": "-",
>   "remoteHost": "192.168.0.1",
>   "message": "GET /metrics HTTP/1.1",
>   "status": 200,
>   "size": "50",
>   "referer": "-",
>   "processTimeMillis": 92
> }
> {code}
> The Attribute "nanoOfSeconds" starts with leading zeros. According to the JSON [rfc4627|https://tools.ietf.org/html/rfc4627] this is an invalid JSON number.
> Is it possible to correct this and remove the leading zeros?
