I am facing strange issue with sonarqube 5.0.1 , one one of the machine it is not starting. Here is the error log - sonar.log -
--> Wrapper Started as D
Could you verify the Java version on the machine starting?
Java 6 is no more supported http://docs.sonarqube.org/display/SONAR/Requirements#Requirements-Prerequisite but from your error message, I don't know if this is the problem you meet.
