All of the config disablement tests (e.g. DisableAnnotationGloballyEnableOnClassTest) use Executors.newFixedThreadPool to create threads to test whether the bulkhead is enabled.
It hasn't been a problem before, but when running in JakartaEE, some things may break when unmanaged threads like these are used so we should avoid them.
