Comment 2

[BugBot [:suhaib / :marco/ :calixte]]

The bug is linked to a topcrash signature, which matches the following criterion:

• Top 5 AMD64 and x86 crashes on release

:cpeterson, could you consider increasing the severity of this top-crash bug?

For more information, please visit auto_nag documentation.

Comment 3

[Chris Peterson [:cpeterson]]

Moving to Fenix's "Experimentation and Telemetry" component because this looks like a Nimbus or Glean bug:

Caused by: java.lang.NullPointerException: Attempt to invoke virtual method 'long java.util.concurrent.atomic.AtomicLong.decrementAndGet()' on a null object reference
	at mozilla.telemetry.glean.internal.EventMetric.record(glean.kt:8)

Comment 4

[Chris Peterson [:cpeterson]]

Christian says this crash is in UniFFI generated code, similar to crash https://github.com/mozilla/application-services/issues/4380.

Comment 5

[Chris Peterson [:cpeterson]]

97% of these crashes are from x86 or x86_64 devices and running old Android 5.0 or 5.1, so lowering priority to P5.

Comment 6

[Kevin Brosnan [Ex-Mozilla]]

The spike is not showing new crashes, the A-C issue 4380 that I filed in August of '21 is the same crash. The signature must have changed in 106.

Comment 7

[BugBot [:suhaib / :marco/ :calixte]]

Based on the topcrash criteria, the crash signature linked to this bug is not a topcrash signature anymore.

For more information, please visit auto_nag documentation.

Comment 8

[BugBot [:suhaib / :marco/ :calixte]]

Sorry for removing the keyword earlier but there is a recent change in the ranking, so the bug is again linked to a topcrash signature, which matches the following criterion:

• Top 10 AArch64 and ARM crashes on beta

For more information, please visit auto_nag documentation.

Comment 9

[BugBot [:suhaib / :marco/ :calixte]]

Based on the topcrash criteria, the crash signature linked to this bug is not a topcrash signature anymore.

For more information, please visit auto_nag documentation.

Comment 10

[Chris Peterson [:cpeterson]]

Adding more crash signatures from Android 5 x86 devices.

Comment 11

[Chris Peterson [:cpeterson]]

[@ java.lang.NullPointerException: at mozilla.appservices.autofill.Store.getAllCreditCards(autofill.kt) ] is another crash signature with the same issue on x86 Android 5 devices.
