Too often, I type something valid and autocomplete doesn't have it listed. The image on the right is an example, but is not the only case where this happens. One example is when I try to create an anonymous instance or method using the new keyword and the autocompletion tool doesn't have it listed.
It's unlikely that autocompletion will become 100% flawless and absolutely never fail, especially at its current stage. Thus, it would be nice to see options to disable autocompletion on space and on semi-colon. Completion on spacebar or semi-colon are hardly necessary with autocompletion on hitting enter. As the autocompletion box appears very often in most code typing and I do not want to nitpick when it appears, it should be relatively simple to not autocomplete on spacebar and semi-colon.
I choose these options to disable because it is often the spacebar which affects me in certain scenarios (such as typing new only to have it be replaced on a spacebar click to NewsStyleUriParser). The semi-colon is said to affect others. If you go here, you'll find the same issue (in Eclipse) shared by many professional and regular Java users. This is an IDE issue, not a language issue. That means that if it's an issue in Eclipse, then it's certainly an issue in other languages.
Please consider adding these very simple features, and thanks for your consideration.
