Description of problem:
SELinux is preventing /usr/java/jre1.7.0_21/bin/java from 'create' accesses on the netlink_socket .

*****  Plugin mozplugger (99.1 confidence) suggests  *************************

If you want to use the plugin package
Then you must turn off SELinux controls on the Firefox plugins.
Do
# setsebool unconfined_mozilla_plugin_transition 0

*****  Plugin catchall (1.81 confidence) suggests  ***************************

If você acredita que o java deva ser permitido acesso de create em  netlink_socket  por default.
Then você precisa reportar este como um erro.
Você pode gerar um módulo de política local para permitir este acesso.
Do
permitir este acesso agora executando:
# grep java /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
