Bootable JAR/Galleon - HTTP 500 is returned by some RESTEasy tests ------------------------------------------------------------------ Key: WFLY-13898 URL: https://issues.redhat.com/browse/WFLY-13898 Project: WildFly Issue Type: Task Components: Build System Affects Versions: 21.0.0.Beta1 Reporter: Fabio Burzigotti Assignee: Jean Francois Denise Priority: Blocker I set the component to {{Build System}} because this only happens with Bootable JAR and - as [~jdenise] noticed - it's related with Galleon. This is about some tests in the RESTEasy TS which has been adapted to execute against bootable JARs through a specific profile [1]. The tests are running successfully with WildFly 20.0.1.Final (the {{ejb}} layer needs to be removed for this experiment to be run [2]) but fail against 21.0.0.Beta1, so it is a regression. Also, the tests are passing when the TS is executed against a distributed WildFly version, and only fail when the server is packaged via the {{wildfly-jar-maven-plugin}}. There are 108 tests failing but htis JIRA focuses on those failing because of the following error: {code} RESTEASY002005: Failed executing POST /all/a/z: org.jboss.resteasy.core.NoMessageBodyWriterFoundFailure: Could not find MessageBodyWriter for response object of type: org.jboss.resteasy.test.validation.resource.ValidationFoo of media type: application/xml;charset=UTF-8 {code} hence I guess serialization issues when the request accept header is not {{application/json}}, e.g. {{org.jboss.resteasy.test.validation.ValidationTest}} *Steps to reproduce*: 1. clone https://github.com/fabiobrz/Resteasy/tree/bootable-jar-support 2. build RESTEasy: {code} $ mvn install -Dmaven.test.skip=true -Dmaven.repo.local=/home/my-local-repo {code} 3. run the test against WF 21.0.0.Beta1: {code} cd testsuite {code} {code} mvn clean verify -am -pl integration-tests -Dmaven.repo.local=/home/my-local-repo -Dserver.version=21.0.0.Beta1 -Dtest=org.jboss.resteasy.test.validation.ValidationTest {code} The test should *pass* 4. run the test against WF 21.0.0.Beta1 with bootable JAR: {code} mvn clean verify -am -pl integration-tests -Dmaven.repo.local=/home/my-local-repo -Dserver.version=21.0.0.Beta1 -Dtest=org.jboss.resteasy.test.validation.ValidationTest -Ddisable.microprofile.tests -Dserver.home=foo -Dts.bootable {code} The test should *fail* 5. run the test against WF 20.0.1.Final with bootable JAR: {code} mvn clean verify -am -pl integration-tests -Dmaven.repo.local=/home/my-local-repo -Dserver.version=20.0.1.Final -Dtest=org.jboss.resteasy.test.validation.ValidationTest -Ddisable.microprofile.tests -Dserver.home=foo -Dts.bootable {code} The test should *pass* [1] https://github.com/resteasy/Resteasy/pull/2526/files#diff-8c7ea03eb619e46...
