CentOS 6.6; java 7: libjli.so cannot be found

**Background:** I have written a Java program to capture network packets. The code uses a wrapper API around libpcap and works nicely – as long as I run the program via **sudo**. I am now trying to figure out how to set up things so that I can run the program as a "regular" user. Ultimately, it will be run on a system where I **do not** have sudo privilege. After some investigation, a possible solution has been found that involves setting capabilities that provide privileged access in a specific way. Part of this involves setting the capabilities CAP_NET_RAW and CAP_NET_ADMIN to ei (e.g., sudo setcap 'CAP_NET_RAW=ei CAP_NET_ADMIN=ei' program). **The Problem:** So, I have done this for the java command on my system. Unfortunately, this has created a problem (which has been asked about by many in various forums) where, when java is invoked, the following message is displayed: >java: error while loading shared libraries: libjli.so: cannot open shared object file: No such file or directory This library does indeed exist and shows up in the list of libraries for the java command.

BTW, I am using the Java 7 JDK, not the OpenJDK. So, what's wrong here? Everything seems to be in place, yet it can't find what it needs. Does the fact that there are two versions of Java on the machine have anything to do it? Is there some other weird situation? Based on my searches, this problem has been encountered by many, but I couldn't seem to find a reason, nor a solution. Can anyone help with this? **UPDATE #1** Well, after a little more investigating, it appears that the problem is due to a "feature" in Java. The link below includes another link that gets to heart of the matter. Problem to launch java at Debian: “error while loading shared libraries: libjli.so” with the embedded link Why setuid java programs don't work . Based upon what I read in these, it would seem that running java with specific capabilities enabled is not allowed. Perhaps that will change at some point, with an improvement to Java security. If anyone knows about this, or more importantly, knows that a solution has been provided, please comment.
