Vijay Kiran Duvvuri updated DNA-499:
------------------------------------

    Attachment: DNA-499.1.patch


First patch wrapping Thread.currentThread.getContenxtClassLoader() with PrivilegedAction.

If the patch is fine, then I'll continue and submit patch for reflection methods.

> Several activities should make use of the Java SecurityManager to ensure the caller has the appropriate privileges to perform the activity.  These activities should be wrapped in a block such as the following:
> String lineSeparator = java.security.AccessController.doPrivileged(
>     new java.security.PrivilegedAction<String>() {
>         public String run() {
>             return System.getProperty("line.separator");
>         }
>     }
>  );
> obviously with the correct generic type for whatever is being returned from the run.  (Nice and concise, huh? Ugh.)
> We need to go through all of the (non-test) code and add this checking (if it is not already there) when the following types of activities are performed:
> - System.getProperty
> - System.setProperty
> - Thread.currentThread().getContextClassLoader()
> - All code executed via reflection
