[jboss-jira] [JBoss JIRA] (ELY-1642) Compilation error on JDK 11: cannot find class sun.reflect.Reflection

    [ https://issues.jboss.org/browse/ELY-1642?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13623953#comment-13623953 ] 

David Lloyd commented on ELY-1642:
----------------------------------

As long as Java 8 support is required, this class needs to be referenced.  Use the jdk-misc artifact via compiler and dependency plugins to add these classes (see https://github.com/wildfly/wildfly-common/blob/master/pom.xml#L116 for an example).  Use the MR JAR build approach to support both old and new APIs (requires that the latest supported JDK be used for build, and that prior JDK(s) be available for test running).
