I think my comment was overly alarming; sorry about that!

What I meant to say was that I have also been working on changing the
way that sysinfo behaves when it is run with a SecurityManager.

Specifically, I am working on the part of sysinfo which analyzes the
classpath, and there are security manager issues involving:
  - is sysinfo allowed to read the java.class.path property
  - is sysinfo allowed to call getProtectionDomain for a class

So I've added some new PrivilegedAction code, and I've added some
new code which catches SecurityException and prints messages trying
to help the user understand the security restrictions they're hitting,
and so forth.

I agree with you that the issues being addressed are independent, and
our two patches don't have to interact at all.

I just wanted to alert you to the fact that we both seemed to be working
in the general area of "sysinfo and SecurityManagers".

thanks,

bryan

P.S. Updated patch for DERBY-668 should arrive this weekend, with changes
incorporating Andrew's feedback (Thanks Andrew!)
