Title: Fixed StringBuilder.insert

Test code:
StringBuilder b = new StringBuilder("test123");
int offset = 2;
char[] str = "ABCD".toCharArray();
b.insert(offset, str, 1, 2);
System.out.println("b: " + b);
System.out.println("str: " + new String(str));

// wrong:
// b: tesest1
// str: ABBC

// right:
// b: teBCst123
// str: ABCD
