I have same problem:
Try this:

For Flash and Java run "system-config-securitylevel" as root and as your user. For each (root and your user) on the SELinux tab under "Modify SELinux Policy" click "Compatibility", then tick the check boxes for "Allow executables to run with executable stack" and "Allow the use of shared libraries with Text Relocation". Then click the "OK" button.
For me it s correct the problem
