Fix Exception Replay in Lambda by shreyamalpani · Pull Request #10380 · DataDog/dd-trace-java

shreyamalpani · 2026-01-14T16:55:59Z

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

Reopens #8849
SVLS-6855
