[jira] [Commented] (CAMEL-14115) InvalidPayloadException when doing GET

["Jan Bednar (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/CAMEL-14115?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16963247#comment-16963247 ] 

Jan Bednar commented on CAMEL-14115:
------------------------------------

camel-http was deprecated many years ago. Switch to [camel-http4 component| https://github.com/apache/camel/blob/camel-2.23.2/components/camel-http4/src/main/docs/http4-component.adoc], which handles this case just fine.

> When looking into HttpProducer.java line 494 I see that Camel tries to transform the body to an InputStream. Why does Camel do that when I do a GET request? A GET request doesn't have a body, so there is no need to even look at the body...
