I have nothing to contribute here, seems like a Java/JNI issue. Maybe escalate to snorp/jchen if Eugen is non-responsive.

Bug 1432235 has only moved files around, which is why it's showing up in blame for a lot of unrelated issues.

If this was a pre-existing issue with different filenames it would be good to find the bug for the old version and dupe it to this one, or at least link them somehow.

I don't know of an existing bug and crash-stats isn't being helpful.
Randall, I think you could reproduce this issue?

I was getting this crash when the GeckoSession had been closed with closeWindow() but was still receiving touch events.

[Milan Sreckovic [:milan] (needinfo for best results)]

Should we be tracking this?

[David Bolter [:davidb] (NeedInfo me for attention)]

Milan, yes thanks.

low volume crash

Resolving as WFM because there have been no crash reports since 60.0.2.
