JaCoCo 0.8.13 fails to instrument DefaultSsmClient (ClassTooLargeException)

### Describe the bug

I see this error when running a Maven build with the JaCoCo code coverage plugin, Java 21, and AWS SDK v2 version `2.31.76`, with the AWS SDK v2 SSM dependency in classpath.

```
java.lang.instrument.IllegalClassFormatException: Error while instrumenting software/amazon/awssdk/services/ssm/DefaultSsmClient with JaCoCo 0.8.13.202504020838/78d5eff`
```

### Expected Behavior

No error emitted

### Current Behavior

Instrumentation error emitted in maven build, see https://github.com/jpalomaki/aws-sdk-java-v2-ssm-jacoco-sscce/actions/runs/16073837387/job/45364298935#step:4:41

### Reproduction Steps

https://github.com/jpalomaki/aws-sdk-java-v2-ssm-jacoco-sscce

### Possible Solution

Can the generated code be modularized better (to not create very large classes)?

### Additional Information/Context

The issue can be worked around by adding an exclusion to the JaCoCo plugin like so:

```xml

software/amazon/awssdk/services/ssm/DefaultSsmClient

```

However, I submitted this issue because I felt that it might be better to optimize the generated code, if possible.
