ITs are not locale acnostic

### Affected version

3.6.2-SNAPSHOT (current master)

### Bug description

Some ITs are failing when the locale is not set to English, e.g. with German locale the IT **jdeprscan-release8** fails

```
assert buildLog.text.contains( "class o/a/m/p/j/its/Deprecations uses deprecated class java/rmi/RMISecurityManager" )

but contains

class o/a/m/p/j/its/Deprecations verwendet die veraltete Klasse java/rmi/RMISecurityManager
```

Start with the jdeprscan-release8 integration test and its assertion on buildLog.text. Reproduce the failure under a non-English locale, then make the test locale-independent; done means the integration test passes with German and English locale settings.
