Subject Re: Http4 component throws useless NPE if request body is String (instead of InputStream)
Date Thu, 16 Aug 2012 06:53:37 GMT
Hi

I upgrade camel-http4 to use 4.2.1 by default in the next 2.11 release of Camel
https://issues.apache.org/jira/browse/CAMEL-5511

I did not spot any NPE, and thus 4.2.1 seems working fine.
