1. Using the Devstudio installer ($ java -jar /notnfs/Downloads/devstudio-11.0.0.GA-installer-standalone.jar), I installed in '/notnfs/devstudio' (not in a home folder), with the default system JVM.
2. On startup (can be from the install, or separately), create a workspace in $HOME/workspace-devstudio.
3. Red Hat Central view loads, with the 'Do Not Enter' icon and the text 'An exception was raised in Javascript'. Clicking on the 'Details >>' button shows the full stacktrace, and it is not logged into the Error Log view.

Note that switching to the Software/Update tab gets the Red Hat Central view to become populated with the correct content so the issue seems isolated to the 'Getting Started' tab.

The relevant part seems to be :
