There are multiple errors in the log after start of 11.0-0.20170804.0022.el7. See the log:

rh-eclipse47.log_clean_start_strict.txt

Interesting is that these errors dissapeared after installation of everything from Central. Maybe we really missing something?

Start of clean Devstudio (and then installation from Central): https://dev-platform-jenkins.rhev-ci-vms.eng.rdu2.redhat.com/view/Devstudio/view/devstudio_rpm_tests/job/rpm_rh_central_UI_test.weekly/33/jdk=openjdk-1.8,label=rhel7-x64-devstudio-11-rpm/artifact/eclipse-log-install-from-rh-central.log

Start after installation from Central (no bundleException):
