Filament: Updating Filament 1.8.1 to 1.9.1 causes JNI crash

[zirman]

Describe the bug
After updating Filament 1.8.1 to 1.9.1 on Android, setting irradiance will cause a SIGSEGV.
A/libc: Fatal signal 11 (SIGSEGV), code 1 (SEGV_MAPERR), fault addr 0x10007

To Reproduce
Here is a sample project to reproduce the issue.
https://github.com/zirman/arcore-filament-example-app/tree/irradience

[zirman]

I get different behavior on Pixel 3 vs. Samsung S9. Samsung S9 does not crash when irradiance is not set. Pixel 3 will crash with our without setting irradiance.

[romainguy]

From what I can tell the crash has nothing to do with setting the irradiance. It's another JNI related issue.

[zirman]

Here are logs for Samsung S9.

[romainguy]

I can't reproduce the issue with our samples. Is there any chance you could share the code of your app or at least an apk? Or explain a bit more what you are doing when rendering a frame? (uploading textures? using external textures? etc.)

[zirman]

Source code is available here:
https://github.com/zirman/arcore-filament-example-app/tree/irradience
Renders detected planes and can place an animated model when touching the screen.

[romainguy]

I think I found the problem in your code in ArCore.kt:

                            setExternalStream(
                                filament.engine,
                                Stream
                                    .Builder()
                                    .stream(arCameraStreamTextureId1.toLong())
                                    .width(width)
                                    .height(height)
                                    .build(filament.engine)
                            )

You are not keeping a reference to the Stream instance. The crash is likely caused because that instance gets garbage collected. Texture doesn't keep a reference to the Java Stream instance.

[zirman]

Interesting. I added reference to the stream instance and am still getting the crash. I normally don't keep references around unless I need it later. It's not clear what needs to be kept from being GC'd.

[romainguy]

Looking into this further not holding onto the Stream object shouldn't cause an issue in your case.

@prideout @bejado can you take a close look at this issue? The crash occurs in nBeginFrame and if the stack trace is correct the crash occurs either because we are attempting to use a JNI ref that's already been destroyed. What's strange is that nBeginFrame does not use any JNI ref, but it could be something that nBeginFrames calls (updating external stream comes to mind).

[romainguy]

CC @pixelflinger in case he has ideas of what could be going on here

[bejado]

I'm able to reproduce on my Pixel 4a. I'll take a closer look at what's happening in nBeginFrame.

[bejado]

I think this has been fixed since 1.9.1. When I replace the Maven dependencies with locally built aar files from the tip of main, I'm no longer able to reproduce. I _am_ able to reproduce when building from the release branch (1.9.1).

Perhaps it was this commit that fixed it?

[romainguy]

Ah that would make sense, we call delete on those refs and they could sometimes be non-initialized.

[romainguy]

Marking as closed since it's now fixed in main. We'll deliver the fix in 1.9.2.
