A minimal working example / reproducer for TOMEE-4342
With OpenEJB 10.0-M1 and earlier versions, ApplicationComposer driven tests (via @RunWithApplicationComposer(mode = ExtensionMode.PER_JVM) do not inject @Resource beans, declared via Properties in an @Application App class.
Those Resouce instances (carrying custom config values) are, however, injected correctly into EJBs or into the App itself. It would be a benefit to have in the Test instance directly.
Interestingly, such resources are injected perfectly fine if the Test is run via the alternative @RunWithEjbContainer test container bootstraper.
