freezes on macOS High Sierra

[iTao8]

1. Open a library
2. double click an entry to open the entry editor
3. freezes

When the entry editor is opened, then move the down arrow to move the entry to the next one, and then freezes

JabRef 4.0-dev--snapshot--2017-09-26--master--35c447bd8
Mac OS X 10.13 x86_64
Java 1.8.0_144

This problem appears on the version snapshot--2017-09-26 and the current one

I can confirm this bug on High Sierra (10.13), which was not there on Sierra (10.12).
This bug only affects the entry editor, but not the about window (which is also a javafx component).
There are no hints in the log files/console output and updating to the java8u152(beta) did not change anything.
Is there any high resolution specific stuff in the entry editor (especially fonts)? @tobiasdiez

[tobiasdiez]

There is no real difference between the entry editor and other javafx implementations (like the groups interface or the search bar). The entry editor however accesses the file system, maybe the problem lies there. Can you please create a thread dump and/or use a debugger to investigate this problem further? Thanks!

There seems to be an issue with the related articles tab.
When I am within the university network, the performance is okish, but otherwise it is not acceptable.

@iTao8 could you please try to disable the "related articles" tab in the preferences (Entry editor -> "Show 'Related Articles' tab"

[iTao8]

@chochreiner The "related articles" tab is always disabled.

[chochreiner]

@tobiasdiez are there any other requests to scientific portals like ieee, acm, ... which could result in a timeout outside of university networks/when the user has no permission to access these services

Potentially #3227?

[manfredlift]

For anyone on macOS Sierra, I had the same issue on 4.0.0 and following the workaround in #3227 fixed it.

[tobiasdiez]

@manfredlift (or somebody else using macOS): you you please add the workaround in the installation notes so that new users find the information more easily. Thanks!

With version 4.0 (on macOS Sierra 10.12.6) I'm getting the freeze after the following steps:

1. "Press the add article button" ;
2. Paste a reference into the "biblatex source" pane after copying from Chrome;
3. Jabref hangs after either a) highlighting a piece of text in the "biblatex source" pane with the cursor, or b) simply selecting the "General" pane.

Appending my host name to localhost in /etc/hosts (and then rebooting) has no effect. This is a machine connected to a university network however. Haven't tried 4.0 at home yet.

Problem seems to be consistently reproducible. :(

I am running into the same error. I downloaded JabRef-4.0.jar from the repo and ran it from the terminal to capture the output. When I first open the program, the output is

Then, when I click on the add entry button and select "Article", an exception is thrown:

I will note that the program doesn't hang when I'm running it in this mode, although it does hang when I run the bundled application version installed by the dmg.

I have now added a note regarding the host mapping solution for the freezes into the installation help. Hopefully, this helps some users to fix their setup instead of reporting an issue here.

@adcox The log says that you have an older JavaFX runtime installed. This might be the reason why some classes cannot be instantiated and trigger a NullPointerException later. Please make sure you have an up-to-date version of JavaFX on your system.
