[ https://issues.jboss.org/browse/WFLY-11178?page=com.atlassian.jira.plugin... ] Jan Blizňák commented on WFLY-11178: ------------------------------------ [~dmlloyd], yeah, I get it, you described desired situation. I tried to prepare a reproducer which should reveal the issue without webservices and without picketlink. It is a copy of WF helloworld quickstart with additional call to "SchemaFactory.newInstance()" and some diagnostic output. To reproduce: # clone https://github.com/jbliznak/reproducer-wfly-11178 # execute server with particular JDK and {{test.use.property}} set to true when {{javax.xml.validation.SchemaFactory:http://www.w3.org/2001/XMLSchema}} property should be set to {{org.apache.xerces.jaxp.validation.XMLSchemaFactory}}, eg. {{JAVA_OPTS="-Djaxp.debug=true -Dtest.use.property=true" bin/standalone.sh}} # deploy the app to running server with {{mvn clean package wildfly:deploy}} # invoke servlet, eg. {{curl http://localhost:8080/helloworld/HelloWorld}} The result with WF 14.0.1.Final class can't be initialized in case of IBM&&property set: ||resolved class ||property unset ||property set || ||OpenJDK| __redirected.__SchemaFactory | __redirected.__SchemaFactory | ||IBM JDK| __redirected.__SchemaFactory | java.lang.IllegalArgumentException: Provider org.apache.xerces.jaxp.validation.XMLSchemaFactory not found | The interesting

that case it's up to them to ensure the dependency is added to the deployment.?? The testing app doesn't have org.apache.xerces module dependency explicitly added, yet OpenJDK can handle situation with property set (looks like OpenJDK has some fallback mechanism which IBM doesn't). Or there might be some classloading issue with IBM. At this point I think JBoss Modules jira could be created for future work on this, WDYT? -- This message was sent by Atlassian Jira (v7.12.1#712002)
