---------------------------------------
Summary: camel-platform-http-vertx: Responses may not complete if
exceptions are thrown in VertxPlatformHttpSupport.writeResponse
Key: CAMEL-20873
URL: https://issues.apache.org/jira/browse/CAMEL-20873
Project: Camel
Issue Type: Bug
Components: camel-platform-http-vertx
Reporter: James Netherton
Assignee: James Netherton
Fix For: 4.4.3, 4.7.0
In VertxPlatformHttpSupport.writeResponse, the only exception that is handled
is when fallback type conversion fails on the message body:
https://github.com/apache/camel/blob/4621c36131a32fa340e6ab5975126d207a104fe5/components/camel-platform-http-vertx/src/main/java/org/apache/camel/component/platform/http/vertx/VertxPlatformHttpSupport.java#L179-L205
However, it can potentially happen that other parts of processing the response,
such as adding HTTP headers, can fail and cause an exception. In this case, the
Vert.x promise is left unfulfilled and thus the response may not complete
correctly.
It is probably better to wrap all of the writeResponse method code in a try /
catch block so the promise can be correctly set in a failed state.
