-----------------------------------
Summary: Exceptions caught during JSON serialisation aren't
handled correctly
Key: CXF-8581
URL: https://issues.apache.org/jira/browse/CXF-8581
Project: CXF
Issue Type: Bug
Components: JAX-RS
Affects Versions: 3.4.4
Environment: OpenJDK 11
Windows 10 x64
Apache CXF 3.4.4
Reporter: Marcel Schramm
When trying to serialize an object that contains unserializable data, cxf runs
into an exception.
An error log message is printed by `JAXRSUtils.logMessageHandlerProblem`.
However, the message contains no stack trace. On top of that the invoking
client receives a `200 OK` HTTP status code and partially written JSON,
followed by an error message.
What I'd have expected instead, is to use the registered `ExceptionMapper`,
which would turn this into an `500 Internal Server Error`. On top of that, it
should print the stacktrace, as it's pretty hard to know what's going on
otherwise.
In our specific case, we had an object that contains a `java.awt.Font` object.
