The QuerydslKeyValueRepository.findOne(Predicate predicate)` method throws Exception when Spring Boot application is run from command-line [DATAKV-237]

[spring-projects-issues]

Valerii Sukhotskyi opened DATAKV-237 and commented

I have created simple Spring Boot + Spring Data Key-Value + Querydsl application (https://github.com/suhotskiy/spring-data-keyvalue-querydsl-bug).
When I run: mvn spring-boot:run all works fine. But when the application is run from the command line: java -jar example-0.0.1-SNAPSHOT.jar the exception is raised:

This seems to have been a Java agent / byte code manipulation problem.

Additionally, this Issue was reported on now, out-of-date Spring Boot and Spring Data versions.

Not certain what the current state of this relationship (Spring + Codegen) would be so closing this ticket.
