spring-boot: ClassCastException post upgrade to 2.6.6

I did upgrade from 2.5.7(jdk-8) to 2.6.6(jdk-11)

I see the below class cast exception ::

java.lang.ClassCastException: class org.springframework.data.couchbase.repository.support.CrudMethodMetadataPostProcessor$DefaultCrudMethodMetadata cannot be cast to class org.springframework.data.jpa.repository.support.CrudMethodMetadata (org.springframework.data.couchbase.repository.support.CrudMethodMetadataPostProcessor$DefaultCrudMethodMetadata and org.springframework.data.jpa.repository.support.CrudMethodMetadata are in unnamed module of loader org.springframework.boot.loader.LaunchedURLClassLoader @8bd1b6a)
at org.springframework.data.jpa.repository.support.CrudMethodMetadataPostProcessor$CrudMethodMetadataPopulatingMethodInterceptor.invoke(CrudMethodMetadataPostProcessor.java:153)

any suggestions?
