Network Server Gives NPE if SQLException has null arguments   (e.g. for ERROR XBM0H)
------------------------------------------------------------------------------------

         Key: DERBY-128
         URL: http://issues.apache.org/jira/browse/DERBY-128
     Project: Derby
        Type: Bug
  Components: Network Server  
    Versions: 10.0.2.1    
 Environment: Linux 
    Reporter: Kathey Marsden
    Priority: Minor


Network server 

 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.
   ERROR XBM0H: Directory /NSinSameJVMTestDB cannot be created.


ERROR XBM0H: Directory /NSinSameJVMTestDB cannot be created.
