FastJson 1.2.37 "unclosed.str" issue with valid input

[greenlaw110]

Note the issue only captured on v1.2.37.

Given two strings below:

String strOk = "{\"v\": 111}";
String strBad = "{\"v\":111}";

Note the only difference is there is a whitespace behind : in strOk.

parsing strOk is fine:

Foo ok = JSON.parseObject(strOk, Foo.class);

This will cause the unclosed.str issue:

Foo bad = JSON.parseObject(strBad, Foo.class);
