AspectJ, multi-context, @Lock: no transaction is in progress

[cdalexndr]

Spring Boot 2.2.5.RELEASE

Sample project: https://github.com/cdalexndr/spring-boot-issue-20683
Run gradlew test

For this error to occur it seems that the following conditions need to be met:

1. Use transaction management with AspectJ
2. Call repository method annotated with @Lock
3. Run tests with multi contexts

I've added the following comments in source: //comment this line for tests to work
If you change the test order, or run only the failed test (single context), then the test will succeed.

Log error:

Thanks for the report and sample project. This doesn't appear to be a Spring Boot problem as it can be reproduced without any involvement from Spring Boot. Here are the changes that remove the use of Spring Boot:

Yeah that looks like it to me too. I am going to close this as duplicate and add this issue to the ones we should follow once it is fixed, especially given we have a sample.
