I have a same problem. Did anyone found a solution?

cforcey commented Mar 4, 2013

For our group, it was a result of our Tomcat start up script setting JAVA_OPTS:

We changed the tomcat script to use CATALINA_OPTS in (xtext)

export CATALINA_OPTS="$CATALINA_OPTS -Xms1024m -Xmx4096m -XX:PermSize=512m -XX:+UseParallelGC"
$EXECUTABLE -Djruby.debug.loadService=true

And then we tweaked out Rails bootstrap to be sure to check for the error:

# patch for avoiding catalina logger getting used in jruby automations
# config/initializers/bootstrap.rb
env_java_opts = ENV["JAVA_OPTS"]
  if(env_java_opts && env_java_opts.include?   ("Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager"))
  Rails.logger.warn("WARNING: Automation may not run properly because JAVA_OPTS couldn't be updated. (#{env_java_opts})")
end"\n**** Automation Configuration ****")"\nRUBY_PATH=#{RUBY_PATH}")"\nJAVA_OPTS=#{ENV["JAVA_OPTS"]}")"\nJAVA_HOME=#{ENV["JAVA_HOME"]}")"\nJRUBY_OPTS=#{ENV["JRUBY_OPTS"]}\n")

Hope this helps. Other insights? C

I'd like to understand why this happens, but I suspect it's going to be very specific to how the server's classloaders work. We have had many classloader improvements since the last comment, and there has been no other insights, so I'm closing this.

FWIW I had this error and it was due to the CARBON_HOME env var not being set, adding a line in my start script eg.
export CARBON_HOME='/path/to/wso2'
made it work
