sonar solaris start problem

first I got

--- Backtrace Gem::LoadError: Could not find rails (= 2.3.14) amongst []

in the log then I start looking here is the solution

1. open SONAR_HOME/conf/wrapper.conf
2. add wrapper.java.additional.3=-Djruby.native.enabled=false

thats it just restart sonar it will start properly :)
