Note that the `WhenUsingAspectJ` tests are still simply verifying structure instead of behavior. This is because the project appearsto be misconfigured in some way such that AspectJ advice isn't getting woven in at runtime. The original Groovy tests also only verified structure and they may be that way for a similar reason.
Either way, I will open up a ticket so we can review why that is the case and if there is a good fix.
Issue: gh-4939
Note that the old groovy test used a configuration of
```
http
.authorizeRequests()
.anyRequest().hasAnyAuthority("USER")
```
However, as I read the issue, gh-2984, the problem this issue
identifies is the non-passive change of defaulting to prefix
ROLE_ with all role-based configuration methods. So, the test now
does the following:
```
http
.authorizeRequests()
.anyRequest().access("hasAnyRole('USER')")
```
which demonstrates, given the configuration in this test, that
ROLE_ is correctly not prefixed in this expression, even though
it is a role-based configuration.
Issue: gh-4939
All tests in `org.springframework.security.config.debug` are migrated.
Note that `SecurityDebugBeanFactoryPostProceessorTest` preserves the original structure-verifying strategy used in the Groovy test. Verifying debug behavior turns out to be fairly tricky since being behaviorally invisible is in its nature.
Issue: gh-4939
This test now checks key and principal both, which differs from the original Groovy test
In order to keep from needing to execute logic internal to `AnonymousAuthenticationToken`, this test changed from the original Groovy test. In the Groovy test, `key` is tested; however in this new test, `principal` is tested instead.
A concern was raised that if `AnonymousAuthenticationProvider` were invoked in this test, then testing only `principal` would not confirm that `key` was correctly propagated to `AnonymousAuthenticationProvider`. So, the test now configures both `key` and `principal`. The former to confirm correct wiring of `AnonymousAuthenticationProvider` and the latter to confirm correct wiring of `AnonymousAuthenticationFilter`.
