When I try to launch an updated Tom cat agent 10.7, I'm getting this Exception:

 

Exception in thread "main" java.lang.UnsupportedClassVersionError: (com/wily/introscope/api/instrument/JavaAgent) bad major version at offset=6

Fatal error: processing of -javaagent failed
 
So by looking at the documentation from the CA APM 10.7 we have to change the catalina.sh with the particular option:
-javaagent:<PathToAgentJar> -DagentProfile=<PathToAgentProfile>
So i change it here and still got the same exception, or it launches but no metrics are shown in the Introscope
CATALINA_OPTS="$CATALINA_OPTS $JPDA_OPTS"
 
What is the difference on changing the catalina.sh and changing on the tomcat conf file? When launching the JVM on this agent 10.7 which file it reads?
CONFIGURATION FILE:(...)Tomcat/conf/instance.conf
" java version "1.7.0"

Can someone guide me to updating this tomcat agent? Doc is a bit misleading.
Thanks
