`@SentryCheckIn` always starts a new trace

[adinauer]

Integration

sentry

Java Version

any

Version

8.27.1

Steps to Reproduce

sentry-java/sentry-samples/sentry-samples-spring-boot-4/src/main/java/io/sentry/samples/spring/boot4/CustomJob.java

Line 14 in 3699cd5

@SentryTransaction(operation = "scheduled")

creates a transaction.

sentry-java/sentry-spring-7/src/main/java/io/sentry/spring7/checkin/SentryCheckInAdvice.java

Line 91 in 4c4fed9

TracingUtils.startNewTrace(scopes);

starts a new trace.

Use our Spring Boot 4 sample to verify.

Expected Result

PropagationContext trace ID matches the transactions trace ID.

Actual Result

PropagationContext trace ID differs from the transactions trace ID.

This might not have any effect in practice because we should be using the span/transaction when retrieving the trace ID.

Just for reference we are now using io.sentry.util.CheckInUtils#withCheckIn(java.lang.String, java.util.concurrent.Callable<U>) to handle the checkin to sentry as we have the same code run under different cron monitor and so can't use the annontations.
