这种行为是故意的吗？

//create the same URI using two different constructors

URI foo = null, bar = null;
try { 
    //constructor: URI(uri string)
    foo = new URI("http://localhost/index.php?token=4%2F4EzdsSBg_4vX6D5pzvdsMLDoyItB");
} catch (URISyntaxException e) {} 
try { 
    //constructor: URI(scheme, authority, path, query, fragment) 
    bar = new URI("http", "localhost", "/index.php", "token=4%2F4EzdsSBg_4vX6D5pzvdsMLDoyItB", null);
} catch (URISyntaxException e) {}

//the output:
//foo.getQuery() = token=4/4EzdsSBg_4vX6D5pzvdsMLDoyItB
//bar.getQuery() = token=4%2F4EzdsSBg_4vX6D5pzvdsMLDoyItB

URI（字符串uri）构造函数似乎正在解码URI的查询部分。我以为查询部分应该被编码？为什么其他构造函数不解码查询部分？
