Failed Starting Designer in Eclipse Java EE Oxygen on RHEL7

I am installing a fresh version of Eclipse Java EE Oxygen on RHEL7. I install the Vaadin Eclipse Plugin by navigating to the Eclipse Marketplace and installing it. After that, I continually get the following error:

An internal error occurred during: “Initializing BrowserCore for Vaadin Designer”.
com.teamdev.jxbrowser.chromium.internal.ipc.IPCException: IPC process exited. Exit code: 1
at com.teamdev.jxbrowser.chromium.internal.ipc.d.run(SourceFile:198)
at java.lang.Thread.run(Thread.java:745)

Changing the Vaadin Designer preferences to enable/disable the JxBrowser has no effect. I don’t see any additional log statements anywhere that might indicate what the underlying issue is.

Any ideas?
