Description of problem:
After I upgraded to Fedora 17, I started having the following warning:

SELinux is preventing java from using the execmem access on a process.

*****  Plugin catchall_boolean (89.3 confidence) suggests  *******************

If si desidera allow httpd scripts and modules execmem/execstack
Then you must tell SELinux about this by enabling the 'httpd_execmem' boolean.You can read 'httpd_selinux' man page for more details.
Do
setsebool -P httpd_execmem 1

*****  Plugin catchall (11.6 confidence) suggests  ***************************

If si crede che java dovrebbe avere possibilità di accesso execmem ai processi etichettati httpd_t in modo predefinito.
Then si dovrebbe riportare il problema come bug.
E' possibile generare un modulo di politica locale per consentire questo accesso.
Do
consentire questo accesso per il momento eseguendo:
# grep java /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
