Hi, on a Gentoo system, it starts, upgrades, then crashes:

Could not find the reason. Any ideas?

@msdobrescu: Please install Java on your system and rename java/jre folder within your JDownloader folder, see https://support.jdownloader.org/Know...tion-directory .
I guess you've installed the installer with bundled java 11? looks like this one has some incompatibility issues with certain hardware.
With renaming the java/jre folder, the launcher will switch to system installed java instead.

[msdobrescu]

I've tried the "other" (MULTIOS JAR without Installer) and the Linux installer, bith have the same issue.

There is a java directory inside jd2 installation, but it is empty.

[Jiaz]

@msdobrescu: What java version are you using? can you provide a log? see https://support.jdownloader.org/Know...d-session-logs
or zip the logs folder and send to support@jdownloader.org

Both having the same issue sounds like your java installation/version is broken or you're having hardware/system issues.

What java version are you using? on console
java -version

[msdobrescu]

java -version
openjdk version "11.0.14" 2022-01-18
OpenJDK Runtime Environment Temurin-11.0.14+9 (build 11.0.14+9)
OpenJDK 64-Bit Server VM Temurin-11.0.14+9 (build 11.0.14+9, mixed mode)

[Jiaz]

@msdobrescu: looks like this java build is broken as the crash happens outside of JDownloader within java itself
You can try to switch to Java 8 or Java 17 or try a different build

Thanks for the logs, yes it's using the java from system and that one is crashing. I would suggest to remove java11 and either install java8 or java17 version

[msdobrescu]

That I suspect too, unfortunately can't confirm, this is the only crashing java app I have.
Would be useful to know what part is broken, otherwise I can't create a ticket for it.

[Jiaz]

@msdobrescu: free(): invalid pointer, java is trying to free memory on invalid pointer. That's all you see there. Doesn't mean java is the cause but also can be broken memory. You should also check memory with memtest86
but I would first check with different java version/build.

Can't help with that as the message does not provide any further hint. Maybe the core dump contains details.

[msdobrescu]

Can you point me where is that core dump? I don't find one in JD's directory, nor in java's.

I'm sorry, but can't help with that. If there is no file in cwd, then most likely the file is too large, see
forums.gentoo.org/viewtopic-t-812901.html

[msdobrescu]

The limit is set to unlimited. Strange to not have a core dump, but may be a different process that causes the crash and need to find that one.

[Jiaz]

@msdobrescu: I would first check if the crash continues to happen with different java version/build. if so, then it's not java but something else.

[msdobrescu]

Hi, I've got a core dump!

Is it java or libc?

[Jiaz]

smells like libc as cause but I'm no expert.I really would recommend to test different java version/build to limit the cause

[msdobrescu]

Sorry, that is not possible, I would do it if I could.

[Jiaz]

@msdobrescu: just download a java build from adoptium.net, extract and use that one to launch JDownloader. no need to change your system java for this.
eg /home/xy/java/bin/java -jar /path../JDownloader.jar

[msdobrescu]

That worked, I confirm there is a bug in distro's java. This worked:

java --version
openjdk 17.0.3 2022-04-19
OpenJDK Runtime Environment Temurin-17.0.3+7 (build 17.0.3+7)
OpenJDK 64-Bit Server VM Temurin-17.0.3+7 (build 17.0.3+7, mixed mode, sharing)

At least we've clarified it!

Thank you!

[Jiaz]

@msdobrescu: that would explain that we had same java version bundled with another installed and also got same reports. Thanks for your time and help on this.
Should take too long for updated java as 11.0.15 is available since a few weeks. see
adoptium.net/de/temurin/releases?version=11
