Darts-java is a good implementation of DAT( double array trie), and I really appreciate your hard work. I developed a project, and some of its code based on your darts-java. darts-java is dual licensed, but I feel confused the words - " It is dual licensed, LGPL and Modified BSD." that comes from the website http://chasen.org/~taku/software/darts/. Can I just choose Modified BSD for my projects only？

Implementation of trie with double arrays. A port of Darts implemented in C++ to Java. Sen, who ported his old MeCab to Java, also has a DoubleArrayTrie with the same name, but since it was old and the license was forked from his LGPL-only state, it was not easy to use, so I rewrote it myself . . It is dual licensed, LGPL and Modified BSD.

i find a bug
in the resize method have a bug;
bug code is
System.arraycopy(used2, 0, used2, 0, allocSize);
right code is
System.arraycopy(used, 0, used2, 0, allocSize);

i have some problem; when i use resize method and setting a small size; but the final build tries is wrong

If the last two characters of the first string in the list are consecutive coding, then only the last character can be queried to return the correct result, which is different from the expected.

Code example：
//list add 123 or 234 or 345
//key = 3 or 4 or 5
//The results are all matchable
DoubleArrayTrie adt = new DoubleArrayTrie();
List list = new ArrayList();
list.add("123");
// 所有词必须先排序
Collections.sort(list);
// 构建DoubleArrayTrie
adt.build(list);
String key = "3";
// 检索key是否完全命中了词典中的某个词
int index = adt.exactMatchSearch(key);
System.out.println(index)
//print result 0

In the function of resize,"System.arraycopy(used2, 0, used2, 0, allocSize)" should be "System.arraycopy(used, 0, used2, 0, allocSize)"

Throw ArrayIndexOutOfBoundsException When Open the File and extract Match Search.
