Removing the default permission java.lang.RuntimePermission stopThread permission from the security policy file prevents threads from being stopped using the Thread.stop() method. This approach is not recommended for trusted, custom-developed code that uses that method because the existing design presumably depends upon the ability of the system to perform this action. Furthermore, the system might not be designed to properly handle the resulting exception. In these cases, it is preferable to implement an alternate design approach corresponding to another compliant solution described in this guidelinerule.
