title: Eclipse internal error "Polling news feeds"
body: <p>I'm using Eclipse(4.9.0) on my MacBook (High Sierra, Java 11) and this error is showing sometimes, if I'm on another app, the errors create a "stack" as you see in the screenshot, it is annoying to come back to Eclipse and to close this error every time.
  Can somebody help me solve this?</p>
