Flowable 6.1.0 snapshot engine, run test failure

I download flowable 6.1.0 snapshot, but run test failure when compile,package for flowable-engine , System message:

Failed tests:
testOrQueryByprocessDefinition(org.flowable.engine.test.api.history.HistoricProcessInstanceAndVariablesQueryTest)
testQueryMessageStartEvents(org.flowable.engine.test.bpmn.event.message.MessageStartEventTest)

Why?

Hi,

Difficult to say without the surefire reports copied in.
We run tests against Github master on every commit and there are currently no test failures (http://qa.flowable.org/view/Version%206/).

Best regards,

Tijs
