Access denied ("java.lang.RuntimePermission") Follow

Problem: When starting to record, the recording toolbar buttons are disabled and the Java applet console displays the following error:
java.security.AccessControlException: access denied ("java.lang.RuntimePermission" "...") 

Solution: Add permissions to java.policy file.
These additional permissions are required starting from Java 8.

Go to the Java installation directory: <java installation>/lib/security/java.policy
On a Dev machine with multiple java versions, you should look for the file in the latest 32bit jre* installation: e.g. C:/Program Files (x86)/Java/jre1.8.0_221/lib/security/java.policy
(the Program Files (x86)/Java/jre, not the Program Files (x86)/Java/jdk/jre)

Append the following at the end of the file :

grant {
 permission java.net.SocketPermission "127.0.0.1:4444", "accept, connect, listen, resolve";
 permission java.net.SocketPermission "127.0.0.1:4445", "accept, connect, listen, resolve";
 permission java.net.SocketPermission "127.0.0.1", "accept, connect, listen, resolve";
 permission java.io.FilePermission "<<ALL FILES>>", "read, write, delete, execute";
};

grant {
 permission java.security.AllPermission;
 permission java.util.PropertyPermission "java.security.policy", "write";
};
