SELinux Blocks Tomcat 7 Service in RHEL 7 after Yum update

I performed a Yum update and Tomcat's ability to access file has been broken.

SEVERE: Failed to load keystore type JKS with path /var/websvr/certs/keyfile.jks due to /var/websvr/certs/keyfile.jks (Permission denied)
java.io.FileNotFoundException: /var/websvr/certs/keyfile.jks (Permission denied)

Even though the tomcat user has ownership and full permissions of not only the file, but the entire directory

-rwxrwxrwx. 1 tomcat   tomcat 4829 Aug 19  2016 keyfile.jks

and I have verified that Tomcat is running under tomcat user. So, why is access still being prevented?

Red Hat Enterprise Linux Server release 7.4 (Maipo)

Edit

From A.B's comment - the /var/log/audit/audit.log :

type=AVC msg=audit(1511208892.087:392): avc:  denied  { read } for  pid=770 comm="java" name="keyfile.jks" dev="xvda2" ino=9641897 scontext=system_u:system_r:tomcat_t:s0 tcontext=unconfined_u:object_r:var_t:s0 tclass=file

So it appears this is SELinux related. I have tried to resolve, but posts like this one require a Red Hat subscription.

Using RH Doc for SELinux & Apache, in conjunction with RH SELinux Doc - I think to resolve this, the keyfile.jks file must be labelled with:

tomcat_t:tomcat_t:tomcat_sys_content_t:s0

which is read-only access for confined user tomcat_t in role tomcat_t. The file is currently labelled:

unconfined_u:object_r:var_t:s0

to get past additional SELinux file restrictions.

Any guidance is appreciated!
