Logstash ERROR: (NameError) cannot initialize Java class org.logstash.plugins.AliasRegistry (java.lang.ExceptionInInitializerError)
For this exception on windows machines I'd changed jvm.options file for parameters
#-Duser.language=en -> -Duser.language=en
#-Duser.country=US -> -Duser.country=US
and assign proper value for ENV['TZ'] if not set.
