One of my PRs failed to build with test time out error: TestTriggerMetricCollectionRedelivery.testTransactedRedelivery

The link to the Travis build: https://travis-ci.org/aerogear/aerogear-unifiedpush-server/builds/147625096

Another build attempt with the same code base finished successfully: https://travis-ci.org/aerogear/aerogear-unifiedpush-server/builds/147625137

Who can take a look at this?

Best regards,
Idel Pivnitskiy
