Fix bug with overflow bits in patricia trie #127

Open emmanuellegedin opened 5 years ago

I noticed an edge case that causes the put method of PatriciaTrie to crash. This happens when one tries to insert some string and also the same string appended with one or more U+FFFF.

For example:

PatriciaTrie<String> trie = new PatriciaTrie<>();
trie.put("a", "0");
trie.put("a\uFFFF", "1");

causes an exception.

This PR fixes the issue.
