示例代码:-

JSONObject json = new JSONObject();
String pair= "{long sting here}";//11586 letter count
json.accumulate("message", pair); 

我使用了以下jar文件:-

推荐答案

最后，我发现了问题，这是由于commons-lang.jar和commons-lang3-3.5.jar冲突引起的.所以我从Gradle任务中删除了commons-lang.jar.现在它可以正常工作了.

Finally I found the issue, This is due to commons-lang.jar and commons-lang3-3.5.jar conflict. So I have removed commons-lang.jar from Gradle task. Now it is working without any issue.
