SpringBoot Failing test for gh-13945

Failing testcase to show the issue. When Spring AOP need method arguments to build a cache key (but probably also on other annotations that require method arguments) the AOP part will fail.

Creating a Mockito mock results in the loss of the debug information needed to read the correct method parameter.

issue: gh-13945

When running the test (locally) it fails with the following exception.

java.lang.IllegalArgumentException: Null key returned for cache operation (maybe you are using named params on classes without debug info?)

Comment From: wilkinsona

Thanks, but this still doesn't reproduce the problem as spring-boot-test is configured to compile with -parameters. Please see my comment on 13945 for why that matters.
