Eclipse (both Juno and Kepler) started crashing after the Ubuntu upgrade from 13.10 to 14.04. They're not crashing after adding:
org.eclipse.swt.browser.DefaultType=mozilla
to configuration/config.ini
(from https://askubuntu.com/questions/457506)
But now the auto-completion has gone.
I updated to java 8, added
org.eclipse.swt.browser.XULRunnerPath=/usr/bin/xulrunner
to configuration/config.ini, using both xulrunner 20 and 29. To no avail.
(from https://bugs.eclipse.org/bugs/show_bug.cgi?id=404776 )
Even a re-install of Kepler doesn't fix the issue.
What can I do to make it work?
Solved it. It turns out that the content assist was there all along (it's working when selected from the context menu). But CTRL+space was highjacked by the input method (IBus). I've deleted the key in the input method and got the content assist back straight away.
