cacerts: Operation not permitted

[MrOmocha]

Hi guys,

I am trying to change permissions of cacerts to add a SSL certificate. Here are my command line outputs.

sh-3.2# pwd
/System/Library/Java/Support/CoreDeploy.bundle/Contents/Home/lib/security
sh-3.2# ls -la
total 296
drwxr-xr-x 3 root wheel 102 Jul 15 2015 .
drwxr-xr-x 4 root wheel 136 Oct 6 09:33 ..
-rw-r--r-- 1 root wheel 231802 Jul 15 2015 cacerts
sh-3.2# sudo chflags -R nouchg cacerts
sh-3.2# sudo chmod 777 cacerts
chmod: Unable to change file mode on cacerts: Operation not permitted
sh-3.2#
​

I don't get it. It used to work. Has Apple changed something here?

Thank you in advance!
