InvertedRadixTree.getKeyValuePairsForKeysPrefixing() returning keys that aren't even in the tree

[GoogleCodeExporter]

Hello, unless I am confused about what to expect, I believe 
getKeyValuePairsForKeysPrefixing() is not returning the correct information.  
In fact, I believe it is returning "keys" that aren't even in the tree.  It is 
returning the values at a node, but not the full key that was stored.

What steps will reproduce the problem?
1. Run the attached TreeTest class.

Here is the output I am getting (using the most recent jar downloaded 
yesterday):

**** Constructing new tree
Added key/value pair: /a/b/ -> 1
Added key/value pair: /a/blob/ -> 2
Added key/value pair: /a/blog/ -> 3

└── ○ /a/b
    ├── ○ / (1)
    └── ○ lo
        ├── ○ b/ (2)
        └── ○ g/ (3)

Keys prefixing /a/blob: {/a/b, 1} {/a/blob, 2} 
Keys prefixing /a/blog: {/a/b, 1} {/a/blog, 3} 


It looks to me like the tree structure is correct, but 
getKeyVAluePairsForKeysPrefixing() is returning the incorrect key/value pairs 
for several values.  For example, with first tree in the example above:
Keys prefixing /: {/, 1}   <-  No key "/" stored; this is the node for /a/b/
Keys prefixing /a/: {/, 1}  <- Ditto; no key / was stored


I am using concurrent-trees-2.1.0.jar on Fedora 17.
