Wrap system access, context class loader access, and reflection with doPrivileged

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
