Variable length keys.

[lantame]

Hello! I'm trying to set up PatriciaTrie as container for IP-table. But unfortunately there's a bug (or feature) in implementation: it does not make any difference between empty sequence of bits and a sequence of 0's.
Moreover, when i try to insert (byte array for simplicity)
trie.put(new byte[]{0}, 5);
trie.put(new byte[]{0,0,0}, 10);
trie.get(new byte[]{0})
It returns 10, so the root is moved to second node and data at first node is discarded. Unfortunately, such behavior is coded deeply inside Trie and cannot be changed by creating custom Analyzer :-(
Do you have any suggestions for me to get real variable-length keys working? Thank you in advance.
