>  Network Server throws an NPE because one of the arguments of the SQLException is null.
 It shouldn't do so.
> To reproduce try to create a database in the root directory on Linux.  Do not run in
security manager.  The trace below came from an extra '/' in the url in NSinSameJVM.java
> The issues are:
> 1)  Network Server throws an NPE because one of the arguments of the SQLException is
null in this code.  It shouldn't do so.
> // arguments are variable part of a message
> 	Object[] args = ce.getArguments();
> 	for (int i = 0; args != null &&  i < args.length; i++)
> 		sqlerrmc += args[i].toString() + separator;
> 					
> 2) This exception seems to have null arguments which doesn't seem right.
