Richard Zowalla resolved TOMEE-2920.
------------------------------------
    Resolution: Auto Closed

Hi there!

We wanted to reach out and let you know that we're currently working on cleaning up open issues in Jira that specifically impact unsupported versions, including 1.7.x, 7.0.x, and 7.1.x.

If you had previously reported this issue on one of these unsupported versions, we kindly ask you to check if the problem still persists and can be reproduced on a supported version such as 8.0.x or 9.0.x. If you find that it is indeed reproducible on a supported version, you're more than welcome to re-open this issue.

Thanks!

>             Project: TomEE
>          Issue Type: Bug
>    Affects Versions: 7.0.0
>            Reporter: David Blevins
>            Priority: Major
>
> In TomEE 1.7 and before the following style of JAX-RS would work as we used Jackson:
>  
> {code:java}
> @POST
> @Produces(MediaType.APPLICATION_JSON)
> public long add(final String data) throws Exception {
>     return 100;
> }
> {code}
> After our switch to Johnzon in TomEE 7, endpoints like the above will generate a 500 error like the one below:
> {code:java}
