-----------------------------------------

Hi Suresh,

I follow the references about userDirName, it appears it's build from System.getProperties() and I see nowhere "userDirName" is modified. If you see an occurence, could you specify where, please?

Anyway, it seems user.dir is only use to create a tree of nested directories in order to perform tests. Maybe it could be remove safely from the jvm argLine used for the tests.

> 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);
