Freeze for few seconds sometimes, on MacOS

[Kurapikov]

JabRef version 5.1 and git 69cc797 on Mac OS X 10.15.7

I have tested the latest development version from git and build it myself, and the problem persists

Steps to reproduce the behavior:

1. Open a bib, my bib is only 89 entries.
2. Switch between entries with left click.
3. Sometimes it will freeze for 5 seconds. When it backs normal, I can switch between entries fluently, but after about 5 senconds, it freeze again for about 5 seconds......

It's very same with @tilltnet in following thread:
https://discourse.jabref.org/t/jabref-5-0-very-slow-update-gui-entries/1930/8

I attached Intellij IDEA profiler snapshot and console output here.

First I run jabref with "--debug" option, and then I attach profiler to it. As soon as the profiler is attched, I switch item and cause a freeze. When jabref is out of freeze, I stop profiler and save the snapshot. The profiling lasts about 5 seconds.

Forgot to mention: JRE/JDK 15.0.2

Still no any respond?

This is not simply a performance problem. It makes JabRef almost unusable under MacOS.

If no one can reproduce this, I can do more digest if you developer can provide some hint.

Thanks.

@Kurapikov Is this #5071? Do you have time to investigate? We have a yourkit profiler license in case you would like to use it to support us! #opensource #freetime

I noticed that only happens on start. But then no longer. I am also using Mac. Have you tried to disable Autocompletion?

@kopper @Siedlerchr

It's not #5071. JabRef 5.0 works fine on my Windows 10 box.

The issue I reported in OP is on MacOS. It happens with a small bib only have ~100 entries.

I saw the video attached in #5071 and found yourkit profiler is much cooler than the one in IntelliJ. I can handle the license so no worry. I don't have much time but I think I can spare some time to do this.

I'll try yourkit these days and see if I can find anything. Hope I can attach a video so you can see what to do next.

Cannot reproduce, using mouse (trackpad) or updown arrows to switch between entries, with a > 400 entry library on:

JabRef 5.3--2021-02-16--5546141
Mac OS X 10.15.7 x86_64 
Java 15.0.2 
JavaFX 15.0.1+1

@Kurapikov are you able to reproduce this on the latest master?

Hi koobs,

I have tried on master 2 weeks ago. Recent days I don't have any time since I'm at deadline of my PhD thesis, and I think the code I tested with is new enough.

So may it be the problem with my bib? I attached my bib file here so would you like to test it?

I'll try my best to follow this issue.

@Kurapikov I found a problem, currently thinking about a solution. You can get these solution as a workaround

Hi @Ali96kz

This workaround solved my problem magically!! Thank you very much!!!!

Hope this bug will be fixed soon.

Possibly useful: Java: no timeout on DNS resolution for code that provides DNS resolution lookups with timeouts (set low)

Might be worth pulling in a well maintained network utilities library if Java (still) doesn't provide DNS timeouts in the standard libraries instead of couture code. There's got to be some goodies out there.

I have the same issue on Manjaro Linux 5.10.18 (XFCE) and the workaround fixed the problem as well.
