Public bug reported:
I noticed the following behavior change in the jps command line tool when
updating from
6b33-1.13.5-1ubuntu0.12.04 -> 6b34-1.13.6-1ubuntu0.12.04.1 on a ubuntu 12.04
64bit system.
Staring point is a java process for apache tomcat running as non-root
user (username openbravo in below example) with pid 1462.
In 6b33 when running jps -l as root it did correctly identify the classname of
the running processes as shown here:
luna686:~# jps -l
1462 org.apache.catalina.startup.Bootstrap
11610 sun.tools.jps.Jps
However after updating the same jps call as root-user does now show:
luna686:~# jps -l
12056 sun.tools.jps.Jps
1462 -- process information unavailable
Which break some custom monitoring of us trying to find tomcat process
via its classname.
Note: Problem only occours when running jps as root user and process in
question is running non-root. When running jps as same user as the
tomcat process is running with then both 6b33 + 6b34 work as expected
