Didier Earith updated VFS-241:
------------------------------
Attachment: AbstractFileObject.java
Hi,
I get the same issue.
The java.lang.NullPointerException is raised in the getParent function of the
AbstractFileObject class :
......
synchronized (fs)
{
// Locate the parent of this file
if (parent == null)
{
parent = fs.resolveFile(name.getParent());
}
}
return parent;
}
name.getParent() can return null (if name is the root).
To fix the issue, I have changed the this function to test the result of
name.getParent() call. If null then return null :
....
synchronized (fs)
{
// Locate the parent of this file
if (parent == null)
{
if (name.getParent() == null) {
return null;
}
parent = fs.resolveFile(name.getParent());
}
}
return parent;
}
(see java source file as attachement).
