In my Spring Boot 1.4.0.BUILD-SNAPSHOT application I'm faced a following issue when run a tests at my Ubuntu server(locally everything work fine):
ERROR o.s.test.context.TestContextManager - Caught exception while allowing TestExecutionListener [org.springframework.boot.test.autoconfigure.AutoConfigureReportTestExecutionListener@3b0090a4] to

UPDATED
Finally I have started my application with an additional VM argument -Djava.security.egd=file:/dev/./urandom as described in this question Spring Boot Actuator application won't start on Ubuntu VPS but still no luck with my tests on this Ubuntu server
