DERBY-6396: NullPointerException in DirFile
Check that the array returned by File.list() is non-null before
attempting to iterate through it. Null is a valid return value.

> We got a NullPointerException trying to start a Derby database in embedded
> mode; the stacktrace indicated it happened in
> org.apache.derby.impl.io.DirFile.deleteAll(); that method got called from
> org.apache.derby.impl.io.BaseStorageFactory.createTempDir().
> After investigating, it appears that the deleteAll() method calls
> "super.list()", which according to the java.io.File specifications, can
> return null. But the deleteAll() method doesn't handle that case gracefully.
