I want to migrate to Wildfly-14 but i'm facing a problem:
A request to the following REST-Endpoint gives different answers in Wildfly-14 and Wildfly-13:
@GET
@Path("data")
@Produces(MediaType.APPLICATION_JSON)
public List<String> getData(@Context HttpServletRequest request) throws NotFoundException {
List<String> l = newArrayList();
l.add("aou");
l.add("äöü");
return l;
}
The german umlaute wont be transportet UTF-8-encoded to the client in Wildfly-14. In Wildfly 13 and before all works fine and the response is send utf-8-encoded.
I found two workarounds:
1. Enhance MediaType with charset so it looks like
@Produces(MediaType.APPLICATION_JSON+";charset=utf-8")
2. Start Wildfly with JAVA_OPTS "file.encoding=UTF-8"
but both settings were not necessary in Wildfly-13
Does anybody have an explanation for the different behavior and a better solution than the two workarounds?
Thank you!
PS: I found out that starting Wildfly-14 with -Dresteasy.preferJacksonOverJsonB=true gives me the expected UTF-8 encoded result.
