Question about JCR nodes and hash code.

[Andre Scheunemann <an...@toonboom.com>]

Hello,

I have a situation where I'm building a cache of JCR nodes and I use 
node.hashCode() as my key.
This works fine for local repository nodes but fails with a remote 
repository accessed through RMI.
With the remote repository I get a different hash code for the same node 
for each search that I perform.
 
Shouldn't  the hash code be always the same for a given node even for 
remote repositories ?

Regards,

Andre

Note that it entirely possible for two different nodes to have the
same hash code! I would strongly advice against using the hash code
for anything like that.

How about using the path of the node as the key? Alternatively, if
your node are all referenceable, you could use UUIDs as keys.
