Java: 1.8.0_60-b27
App: tomcat-based single webapp under jsvc

sudo java -jar ~/bin/sjk.jar ttop -p 21787 -n 20 -o CPU

The actual result:
Failed to access MBean server: 21787

But with a socket it works.

Java attach is working though files created in default temp directory. If tomcat process is using different temp directory, it would be invisible. If you have -Djava.io.tmpdir option for your tomcat, try to use same option for SJK.
BTW
Does sjk jps show your tomcat process?
PS
-X option should print full stack trace for error
