Reading Kafka messages is not reflected in the Application Insights as requests since upgrading to Spring boot 4

[apokralipsa]

Expected behavior

A <topic-name> process request is created when application receives a message.
Custom events published in the same thread have the operation_Id and operation_parentId filled based on the W3C traceparent header in the Kafka message.

Actual behavior

The requests are not present anymore. The custom events have the fields empty.

I have created a repository with a minimal reproduction of this issue. Please note the description in the README.md.

The example shows that the OpenTelemetry spans are no longer created with valid traceId / spanId. This makes the SpanContext invalid, so the tracing is not continued in BytecodeUtilImpl.

System information

• SDK Version: 3.7.7
• Application Server type and version (if applicable): Spring boot 4.0.2
• Using spring-boot? Yes

This should get resolved once we update to the latest OpenTelemetry Java Instrumentation.
