Entry-editor typing lag

[wujastyk]

I am experiencing terribly slow data entry in the entry-editor. I first reported this in #4526, but I'm making a separate report here for clarity's sake. This makes the present JabRef snapshot unusable.

JabRef 5.0-dev--snapshot--2018-12-14--master--49c3ef396
Linux 4.15.0-42-generic amd64
Java 1.8.0_191

Both in the field-tabs, and in the biblatex area, it can take two seconds from keypress to the appearance of a single character on the screen. Needless to say, Jabref 5 is unusable until this is improved.

Autocompletion is off.

Jabref 4.3.1 works fine.

My biblatex database has about 4000 entries (here's a link, if you want to examine it). With a smaller database the typing works much better. Still not quite at system-speed (compared against a terminal window). But definitely in the range of normal data entry.

No improvement with the latest changes, unfortunately.

This screencapture illustrates the lag between typing and the appearance of characters on the screen. I was whacking the keys somewhat to make sure they were audible. :-)

So much improved! Using 5.0 now possible again. Thank you!
