QUESTION
Good afternoon everyone,
My problem: I can't seem to make a java agent (https://github.com/krpors/delver) work on WildFly10.1.final
I deployed the same demo spring-boot application(war) on both tomcat and Wildfly
adding the agent to tomcat was straight forward and easy (having only to add the -javaagent:... argument to CATALINA_OPTS) the tomcat server started and the agent worked exactly as expected (listing all the methods in the specified packages in the XML config file of the agent and tracking how many times the method was called and for how long ...)
when everything seemed to work flawlessly with tomcat and the agent I tried to add the delver agent to WildFly and that's when everything started to go wrong.
It took me solid 4 days to get the wildly 10.1 server to start with the agent by adding these configs :
