to be related to upstream issues https://bugs.eclipse.org/bugs/show_bug.cgi?id=541266 and https://bugs.eclipse.org/bugs/show_bug.cgi?id=542689 where recommenders doesn't work with Java 11 and has been removed by upstream eclipse and by the Red Hat Eclipse RPM packages https://issues.jboss.org/browse/RHECLIPSE-82. I don't see a way to disable recommenders in codeready studio.
