Cannot locate symbol "JNI_OnLoad_awt" #970

mipastgt · 2021-07-28T10:43:10Z

I can build my app for Android without problem on a cloud Linux server and install it on my phone locally on a Mac but when I try to run it, it immediately crashes with the following message:

This looks very much like the bug reported here: oracle/graal#3406
This stops me from creating and using any Android app with JavaFX. Is there any solution or workaround for this problem?

Expected Behavior

It should run and not crash.

Current Behavior

It crashes.

Steps to Reproduce

I cannot provide a simple example myself but see link above.

Your Environment

Built on a cloud instance of Ubuntu at Hetzner with gluonfx-maven-plugin 1.0.3 and graalvm-svm-linux-gluon-21.2.0-dev. APK copied to macOS and installed via adb on a Samsung Galaxy S7.

The text was updated successfully, but these errors were encountered:

mipastgt · 2021-07-28T15:55:48Z

A little update:

I ran my program on desktop with the VM option -verbose:class and could not find any AWT reference in the log. So, I have no idea what triggers loading the AWT library.

I also tried the tiny reproducer here. After updating it to use the latest version of the gluonfx-maven-plugin I can confirm that it still reproduces the error.

jperedadnr · 2021-07-29T14:46:37Z

@mipastgt Can you test if your issue gets solved with the plugin snapshot?

version: 1.0.4-SNAPSHOT
repository:

    <pluginRepositories>
        <pluginRepository>
            <id>Snapshots</id>
            <url>http://oss.sonatype.org/content/repositories/snapshots/</url>
        </pluginRepository>
    </pluginRepositories>

mipastgt · 2021-07-29T16:11:19Z

The plugin has not yet been uploaded to https://oss.sonatype.org/content/repositories/snapshots/com/gluonhq/gluonfx-maven-plugin/
(Shouldn't it be https in your snippet above?)

jperedadnr · 2021-07-29T16:17:32Z

Right, it wasn’t published yet. It is now

mipastgt · 2021-07-29T16:37:59Z

It doesn't work yet but at least I get another error message :-( (Again AWT related.)

jperedadnr · 2021-07-29T16:56:18Z

Ok, that was somehow expected.
Can you find libsubstrate.so under target/gluonfx and run and post the output of:
nm libsubstrate.so | grep -i awt

mipastgt · 2021-07-29T17:05:26Z

Do you really mean libsubstrate.so? I only have a libmpCoPilotApp2.so in target/gluonfx/aarch64-android.
In case you mean that, the output is:

Yes, that’s what I need, thanks. We need to remove that U(ndefined) symbol

That's what I thought. There seems to be only this single one in there.

Should we reopen this issue so that the new problem does not get forgotten or would you rather create some new (umbrella ?) issue?

johanvos · 2021-08-01T18:56:50Z

Probably best to open a new issue, as this is something that might happen more frequently when using new GraalVM versions.
I created a new label "nosymbol" for this that can be applied to similar issues.

@johanvos I did as you suggested but it seems only repo-owners are able to add labels. (Verified agains my own repos, where I can do that.)
