Jean-Louis Monteiro commented on TOMEE-2920:
--------------------------------------------

I think this has been fixed in Johnzon and should be resolved with 1.2.9 upgrade.  
When you have a sec, can you double check?
I'll do the upgrade in a minute

> 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:

> @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}
