It actually appears to be a security manager issue as it doesn't 
reproduce with -noSecurityManager  and the actual error in the derby.log is.

I am guessing it is there is an unreported security exception in  
LogFile where we call

protected boolean privExists(StorageFile file)
     {
         return runBooleanAction(0, file);
     }

     private synchronized boolean runBooleanAction(int action, 
StorageFile file) {
         this.action = action;
         this.activeFile = file;

         try {
             return ((Boolean) 
java.security.AccessController.doPrivileged(this)).booleanValue();
         } catch (java.security.PrivilegedActionException pae) {
             return false;
         }
     }

I put a 10.7  build over there which prints a stack trace when a 
permission error occurs to  find out what  the exception  is exactly 
happening of course it did not reproduce.      I am going to narrow the 
10.6 reproduction a bit and then file a bug.  Then I will  check out the 
10.6 branch  and work with that.  Sorry for all the verbosity, but since 
I think it might be a show stopper I thought it good to send updates.
