Disable statement completion on space in Eclipse Content Assist

Question

Is there a way to disable auto-completion feature of Eclipse, which inserts currently selected statement in Java Content Assist when pressing space?

I still want to have such a behavior for enter key (and only for enter).

Answer 1

Since Eclipse 2018-12 (4.10) there is a preference for that:

In Window > Preferences: Java > Editor > Content Assist check the checkbox Disable insertion triggers except 'Enter'
