[limo520]

Describe the bug

When a project depends kotlin-stdlib without kotlin-reflect, upgrading springdoc-openapi-starter-webmvc-ui from 2.7.0 to 2.8.0 will result in java.lang.ClassNotFoundException: kotlin.reflect.full.KClasses

To Reproduce

1. A simple boot project depends kotlin-stdlib without kotlin-reflect
2. upgrading springdoc-openapi-starter-webmvc-ui from 2.7.0 to 2.8.0
3. Visit /swagger-ui/index.html and the exception happened

Expected behavior
No exception is expected.

[Xzuner]

same issure here,using 2.8.0
Handler dispatch failed: java.lang.NoClassDefFoundError: kotlin/reflect/full/KClasses

[yolopunk]

need set properties springdoc.enable-kotlin=false

the default value is true

[sergeykad]

Adding the configuration does not feel like a proper solution for this. I was not even aware till now that we have a transitive dependency on kotlin-stdlib through resilience4j-retry.
