title: Java RMI with no SecurityManager
body: <p>I have some older code that doesn't use a SecurityManager but does use RMI.  From what I have read RMI requires a security manager, but the code seems to work and run fine on the same machine and between two machines.  I have tested this stuff on 1.5, but not on 1.6.</p>
  
  <p>I can't find any resource that discuss when a SecurityManager is required and when it isn't, or if that requirement changed with Java Versions.</p>
  
  <p>I am going to update the code to use one, I just wanted to understand the details behind it.</p>
  
  <p>Thanks for any feedback!</p>
