Question

我的应用程序抛出了StackOverflowError。发现我们的应用程序以JSON的形式记录了Exception，并且代码如下。

GSON.toJson(object) //here object can be my application exception or any runtime exception

令我惊讶的是GSON.toJson抛出了StackOverflowError。

尝试以下设置验证：

public static void main(String[] args) {
    Gson GSON = new Gson();
    GSON.toJson(new NullPointerException());
  }

堆栈跟踪：

    at com.google.gson.internal.bind.ReflectiveTypeAdapterFactory$Adapter.write(ReflectiveTypeAdapterFactory.java:195)

有人能说出为什么我不能获得任何例外的JSON吗？

注意：这仅在我们的应用程序中发生

升级到版本Gson 2.6.1解决了问题

GSON.toJson（new RuntimeException（））抛出StackOverflowError
