Not like this

BaseKarafDefaultFrameworkDuplicatedPropertyEntryFromFileTest.java

 @Test
    public void testConfiguration_shouldHaveWrittenTheLaterOne() throws Exception {
        ServiceReference[] allServiceReferences = ctx.getAllServiceReferences(ConfigurationAdmin.class.getName(), null);
        for (ServiceReference serviceReference : allServiceReferences) {
            ConfigurationAdmin service = (ConfigurationAdmin) ctx.getService(serviceReference);
            try {
                org.osgi.service.cm.Configuration configuration = service.getConfiguration("tests");
                assertEquals("myvalue2", configuration.getProperties().get("mykey"));
                return;
            } catch (Exception e) {
                // continue
            }
        }
        fail();
    }

I like it when the code is both functional and self-critiquing.
