Exception messages can be incorrectly deobfuscated

[PhilGlass]

Integration

sentry-android

Build System

Gradle

AGP Version

9.2.1

Proguard

Enabled

Other Error Monitoring Solution

No

Version

8.33.0

Steps to Reproduce

1. Have an exception with the message string/pay_anyone_cancel_dialog_positive: requested 'en-IE', got 'en'.
2. Have a proguard mapping file that happens to contain the entry com.monzo.standin.screens.accountslist.AccountsListFragmentKt$$ExternalSyntheticLambda19 -> en:

Expected Result

en should stay as en.

Actual Result

en gets deobfuscated to com.monzo.standin.screens.accountslist.AccountsListFragmentKt$$ExternalSyntheticLambda19.

(I realise there's no straightforward way to tell whether some arbitrary word is an obfuscated class name - just thought I should report this)

We also have stuff like this in our mapping file, so I'm guessing this is happening fairly often. 😅

com.monzo.standin.screens.accountslist.AccountsListFragmentKt$$ExternalSyntheticLambda15 -> an:
com.monzo.plans.signup.selection.dialog.ActionableErrorViewModel$State -> or:
com.monzo.businessaccountingintegration.auth.AccountingIntegrationAuthCoordinator$$ExternalSyntheticLambda1 -> ok:
com.monzo.unifiedsearch.UnifiedSearchEvent$ShareExport -> yes:
com.monzo.challenge.acknowledgementprompt.AcknowledgementPromptAuthenticationEvent -> no:
