QuarkusUnitTest: JAXB class loaded twice using two different class loaders if it is both the return type and an argument of a service method #2010
Description
There is a reproducer in https://github.com/ppalaga/quarkus-cxf/commits/i2010/
Steps to reproduce:
git clone https://github.com/ppalaga/quarkus-cxf.git
cd quarkus-cxf
git checkout i2010
# build all
mvnd clean install -DskipTests -Dquarkus.build.skip
# run the failing test
cd extensions/core/deployment
mvnd clean test -Dtest=IncludesConflictJava2WsTest

Note that the test passes when the last commit in branch i2010 is reverted
Also note that the same scenario works flawlessly, it it is run directly using Maven, i.e. not via QuarkusUnitTest.
When debugging, one can see that one io.quarkiverse.cxf.deployment.test.Fruit is loaded using the tests class loader and the other one using application class loader.
