Test failure of WSProviderTestCaseForked on JDK11+Windows --------------------------------------------------------- Key: JBWS-4160 URL: https://issues.jboss.org/browse/JBWS-4160 Project: JBoss Web Services Issue Type: Bug Components: jbossws-cxf Affects Versions: jbossws-cxf-5.2.4.Final Reporter: Jan Blizňák Priority: Major We are seeing failing test org.jboss.test.ws.jaxws.smoke.tools.WSProviderTestCaseForked#testOutputDirectory https://github.com/jbossws/jbossws-cxf/blob/jbossws-cxf-5.2.4.Final/modul... The error message is: {code:java} java.lang.reflect.InvocationTargetException at org.jboss.test.ws.jaxws.smoke.tools.WSProviderTestCaseForked.testOutputDirectory(WSProviderTestCaseForked.java:105) Caused by: java.lang.ClassNotFoundException: org.jboss.test.ws.jaxws.smoke.tools.jaxws.AddResponse at org.jboss.test.ws.jaxws.smoke.tools.WSProviderTestCaseForked.testOutputDirectory(WSProviderTestCaseForked.java:105) {code} During the test this is called https://github.com/jbossws/jbossws-cxf/blob/jbossws-cxf-5.2.4.Final/modul... after which "target/wsprovide/java/org/jboss/test/ws/jaxws/smoke/tools/jaxws/" should contain both *.java and *.class files but it does not on Win+JDK11. The cause of the test error message is then the fact there are no *.class files in tested directory. In case of JDK11 the Jdk9PlusJBossModulesAwareCompiler is used which then calls JDK internal compiler task https://github.com/jbossws/jbossws-cxf/blob/jbossws-cxf-5.2.4.Final/modul... which should create these files. When I was trying to debug it on both Win and RHEL with JDK11 and compare results, there seems to be no relevant difference at what parameters are passed to methods up to this point.
