During the testing of 3.27.2.CR1, one of our tests UniFailureCacheIT.testConcurrentAccessAndRecovery  is failing in native mode with error:  

AssertionFailedError: Cache lock should prevent excessive calls. Expected <= 2, but was 3  

This is a known upstream Quarkus issue where @CacheResult annotation does not properly synchronize concurrent access whe the first Uni fails.
Upstream issue: https://github.com/quarkusio/quarkus/issues/51928#issuecomment-3776949738 

There is a fix PR here: https://github.com/quarkusio/quarkus/pull/52150 (milestone 3.32) but was not backported to 3.27 branch.

I hit this failure in our native  Jenkins job (but it's not exclusive occurs on native) :
