I'm using Splunk OTEL 0.17.0, and version 1.2.2 of https://github.com/google/desugar_jdk_libs/
This is happening on OS 7

[ber4444]

Actually it's happening on any OS versions

[ber4444]

A fix is downgrading the desugaring library to '1.1.5'

[ber4444]

okay, so this was reported here: https://issuetracker.google.com/issues/243636261

[mateuszrzeszutek]

Hey @ber4444 ,
We're actually using desugar_jdk_libs version 1.1.6 in this project:

splunk-otel-android/splunk-otel-android/build.gradle.kts

Line 71 in 00c8329

coreLibraryDesugaring("com.android.tools:desugar_jdk_libs:1.1.6")

Can you try using that version? (I suppose 1.1.5 would probably be fine as well)
We cannot do anything about bugs in the desugaring lib itself in this project, we can only recommend the version that's working for us.

[mateuszrzeszutek]

Hey @ber4444 ,
You can now use desugar_jdk_libs 1.2.2 with AGP 7.3 -- we've switched to that version in #371

[ber4444]

This should not have been closed.

I tried with 1.2.2 but still crashing with a very similar stack trace:

The Google issue I linked to says

This is fixed in 2.0+ which is to be released,
I don't see any way to implement a good fix in 1.2.

[mateuszrzeszutek]

Hey @ber4444 ,
We actually went back to version 1.1.8 in #373
(1.2 for some reason worked, but only on my machine 😅 )
Can you try using 1.1.8 and check if this issue still persists?

[breedx-splk]

Hi @ber4444 . This issue looks to be stale (almost a year old now with no reply). Can you reply with the latest results or otherwise let us know if this is still an issue?

[breedx-splk]

Please reopen if still relevant. Thanks!
