Re: Invalid character found in the request target TomEE 10.0.1

[Richard Zowalla]

GET with a (JSON) payload is against the RFC; a GET with a payload has no 
defined semantics: https://datatracker.ietf.org/doc/html/rfc7231#section-4.3.1

That being said, „data“ is appended to the URL as query parameters, the content 
type is ignored and the JSON strings will appear (encoded) in the URL.

I would suggest to switch to POST here … if you insist on GET, you need to 
correctly encode the json into a query parameter.
