      Description

      ADDITIONAL SYSTEM INFORMATION :
      4.4.0-146-generic #172-Ubuntu SMP Wed Apr 3 09:00:08 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux
      openjdk version "1.8.0_191"
      OpenJDK Runtime Environment (build 1.8.0_191-8u191-b12-2ubuntu0.16.04.1-b12)
      OpenJDK 64-Bit Server VM (build 25.191-b12, mixed mode)

      mvn -version
      Apache Maven 3.3.9
      Maven home: /usr/share/maven
      Java version: 1.8.0_191, vendor: Oracle Corporation
      Java home: /usr/lib/jvm/java-8-openjdk-amd64/jre
      Default locale: en_US, platform encoding: UTF-8
      OS name: "linux", version: "4.4.0-146-generic", arch: "amd64", family: "unix"

      So Java is OpenJDK from Ubuntu 16.04 repository, same goes also for maven.

      A DESCRIPTION OF THE PROBLEM :
      When I run my projects JUnits with "mvn verify" command some times JVM crashes. I haven't seen this crash happing in CI or when running JUnits from Eclipse. Crash always happens in same JUnits Running org.openRealmOfStars.game.GameTest which are probably the heaviest JUnits.

      STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
      Goto https://github.com/tuomount/Open-Realms-of-Stars/ and clone my project latest master.
      Then just run "mvn verify". This command probably needs to run quite many times since it happens occasionally.

      ---------- BEGIN SOURCE ----------
      I haven't been able to isolate the source code what is causing this. Is there something that could said on hs_err_pid5369.log?
      ---------- END SOURCE ----------

      CUSTOMER SUBMITTED WORKAROUND :
      Workaround is simply rerun the tests.

      FREQUENCY : occasionally
