Open dialog crashes Processing on Linux

Description

Open project crashes Processing

When you click file – open, the Processing IDE closes.

Expected Behavior

An open file dialog appears letting you choose a folder.

Current Behavior

Nothing happens for several seconds and the Processing IDE closes without any notice. This is 100% reproducable.

Strange: I can pick projects from the recent-list, but am not able to open from the files menu.

Steps to Reproduce

1. Start Processing
2. Click File – Open…

Your Environment

• Processing version: 1275 (4.0a6-1 in Manjaro's repository)
• Operating System and OS version: Manjaro Linux

$ cat /etc/lsb-release
DISTRIB_ID=ManjaroLinux
DISTRIB_RELEASE=21.1.0
DISTRIB_CODENAME=Pahvo
DISTRIB_DESCRIPTION="Manjaro Linux"
$ uname -a
Linux xmg 5.12.19-1-MANJARO #1 SMP PREEMPT Tue Jul 20 20:57:37 UTC 2021 x86_64 GNU/Linux

Have you tried with one of the downloads that we provide? https://github.com/processing/processing4/releases

Thank you for the quick response and the hint!

Not until now. Downloaded, ran install.sh, clicked icon – same behaviour. Started directly from folder, so messages popped out:

Is the installed Java version of concern, or does Processing bring a JRE of its own? Hoewever, this is my Java:

$ java -version⮨
openjdk version "16.0.2" 2021-07-20
OpenJDK Runtime Environment (build 16.0.2+7)
OpenJDK 64-Bit Server VM (build 16.0.2+7, mixed mode)

This is the log file mentioned above :
hs_err_pid68469.log

Ok, the Illegal Reflective Access message is a red herring (see #207) but the crash is something happening in the JVM.

I don't test on Java 16 (11 is what's supported) but if you have 16 working, I would try:

cd /path/to/processing-4.0a6
mv java java.hiding
ln -s /path/to/your/jvm/folder ./java

The exact path you're using for the link should ensure that from inside the Processing download, ./java/bin/java points to the java binary.

Also, given that it's crashing on Open, it probably means there's a bad interaction between your Window Manager and the file selector. You might try editing preferences.txt to set:

chooser.files.native = true

to

chooser.files.native = false

Or vice-versa, if it's already set to false.

Ben,

chooser.files.nativewas set to true in ~/.processing/preferences.txt and setting it to false did the trick (in both, the installed instance as well as in the downloaded image) and I now see a file open dialog in the Java-style!

Seemingly, there is some incompatibility with the file open routine of Manjaro's (and presumably Arch's as well).

Thanks a lot and sorry for bothering you – I might have figured that out on my own.

Cheers from Vienna/Austria

Glad it worked; thanks for the update.

Thank you for the info. I had the same thing on Arch, needs to be chooser.files.native=false.

By the way the path is now .config/processing/preferences.txt (4.x) and no longer .processing/preferences.txt (3.x), at least on my system. Changing the latter has no effect in my Processing 4.

The config change was requested here: #203 and also described in the release notes for beta 1: https://github.com/processing/processing4/blob/master/build/shared/changes.md#features-and-updates

No issue with the change at all :-) I only replied in case someone finds this thread, changes the setting in .processing/preferences.txt and it continues to crash.
