Test  harness should not change the user.dir property , it is meant for 
infomative purpose only.

         Key: DERBY-577
         URL: http://issues.apache.org/jira/browse/DERBY-577
     Project: Derby
        Type: Improvement
  Components: Test  
    Reporter: Suresh Thalamati
    Priority: Minor


If  the  user.dir property is changed ,  you wil  find IO calls are working on 
different directory than what is returned  by 
File.getAbsolutePath()   if the file handle is created with a relative path  
because of JVM issue: 4117557 
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=4117557

I think  it  is  not good  idea for test harness to change  the user.dir 
property.    It makes hard to debug tests ,  because 
files  are not created  at  diferent location than  what is returned by 
getAbsolutePath().    Atleast,   I had  fun time figuring out this :-)

user.dir  is being  changed at the following code segment :
org.apache.derbyTesting.functionTests.harness. RunTest.java 
 testJvmProps.addElement("user.dir="+userDirName);
