Indeed, testing 175, Tomcat 9 now needs JAVA_OPTS="--add-modules java.xml.ws" to run (otherwise that module isn't available). Also, although "illegal" access is enabled by default, it now outputs this: WARNING: An illegal reflective access operation has occurred WARNING: Illegal reflective access by org.apache.catalina.loader.WebappClassLoaderBase (file:/home/remm/Work/jbossweb/apache-tomcat-trunk/output/build/lib/catalina.jar) to field java.lang.Thread.threadLocals WARNING: Please consider reporting this to the maintainers of org.apache.catalina.loader.WebappClassLoaderBase WARNING: Use --illegal-access=warn to enable warnings of further illegal reflective access operations WARNING: All illegal access operations will be denied in a future release We've had to add workarounds for years due to the JDK having issues, and some still being there (direct byte buffers still won't GC properly and need creative reflection tricks).
