Fix Exception Replay in Lambda by jpbempel · Pull Request #10505 · DataDog/dd-trace-java

jpbempel · 2026-02-02T20:04:07Z

What Does This Do

In Lambda, the inner stack trace is truncated -- stack frames from fileName='AWSLambda.java' are removed. Therefore, in the original code, we would end up with a negative currentIdx, resulting in an error occurring in sanityCheckSnapshotAssignment. This PR adds a fallback to fix the mismatched pointer.

Motivation

SVLS-6855

Additional Notes

Related to #10380 & #8849
