Jetty doesn't show up in jcmd

When I launch jcmd it shows me all java processes except Jetty, why?

JCmd:

[root@test_app_bm 2015_06_01_18_19_47_13098]# /usr/java/latest/bin/jcmd 
15152 sun.tools.jcmd.JCmd
21785 DummyTrkPartner.jar

Ps aux:

[root@test_app_bm 2015_06_01_18_19_47_13098]# ps aux | grep java
jetty    13098 13.8 74.4 7048352 2957192 ?

Check your /tmp:

drwxr-xr-x. 2 lace     lace     4096 Oct  9  2021 /tmp/hsperfdata_lace/
drwxr-xr-x  2 reguser  reguser  4096 Feb 22 16:40 /tmp/hsperfdata_nobody/
              ^^^^^^^  ^^^^^^^       MISMATCH                     ^^^^^^
drwxr-xr-x. 2 root     root     4096 May 11 18:22 /tmp/hsperfdata_root/

Each /tmp/hsperfdata_XXX directory should be owner by user XXX.

Sounds like a permissions issue. From your console excerpt, I see "jetty" running as a user, with you being logged in as root.

Run the command as the user "jetty" and you should be able to run jcmd.
