**Kibana version** :7.15.2

**Elasticsearch version** :7.15.2

**APM Server version** : 7.15.2

**APM Agent language and version** : opentelemetry/java 1.9.1 and OLTP exporter

**Description of the problem including expected versus actual behavior. Please include screenshots (if relevant)**:  
Stack trace from Spring Reactive code isn't correctly parsed in the APM

 ![1.APM-no-stacktrace](https://us1.discourse-cdn.com/elastic/original/3X/f/e/fe4f4ebfdcd801c4439478263754532c1e2a3b17.png)

When I open that document in Discover I can see that `error.exception.attributes.stacktrace` field is present but it's in plain text and not parsed. Errors with stack trace have different fields such as `error.exception.stacktrace.classname` and `error.exception.stacktrace.filename` and `error.exception.stacktrace.line.number`

 ![2. Document](https://us1.discourse-cdn.com/elastic/original/3X/3/2/32a44b20c729796bd194a1e99a2c2f9394371732.png)

**Steps to reproduce** :

1. Setup development environment using docker-compose [Quick start development environment | APM Overview [7.15] | Elastic](https://www.elastic.co/guide/en/apm/get-started/current/quick-start-overview.html)

2. Simulate application exception. Checkout Gradle java project from [GitHub - vyhid/otel-missing-stack: OpenTelemetry missing reactive stacktrace](https://github.com/vyhid/otel-missing-stack)  
and run [ExceptionTest] ([otel-missing-stack/ExceptionTest.java at master · vyhid/otel-missing-stack · GitHub](https://github.com/vyhid/otel-missing-stack/blob/master/src/main/java/ExceptionTest.java)) with next VM options  
`-javaagent:"opentelemetry-javaagent-9.jar" -Dotel.resource.attributes=service.name="otel-test" -Dotel.exporter.otlp.endpoint=http://localhost:8200 -Dotel.javaagent.debug=true`

3. Check that the exception is recorded as an error in Elasticsearch, and observe that the stack trace is missing from the span or error UI.

@Andrew_Vyhidnyi would you be able to paste the `error.exception.attributes.stacktrace` as text (not an image) please? That would speed up the process of identifying the issue.

Thanks! I've opened [processor/otel: Java exceptions thrown by Spring Reactive are not parsed correctly · Issue #6893 · elastic/apm-server · GitHub](https://github.com/elastic/apm-server/issues/6893) to track a fix for this
