StackOverFlow while converting a null object to json #622

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago
What steps will reproduce the problem?
1. create a null object activity
2. use gson.toJson(activity)
3. then cause stack overflow

What is the expected output? What do you see instead?

public String toJson(Object src) {
    if (src == null) {
      return toJson(JsonNull.INSTANCE);
    }
    return toJson(src, src.getClass());
  }

when you input a null object , it will create a null instance, then again and 
again

What version of the product are you using? On what operating system?

compile 'com.google.code.gson:gson:2.2.4'
on Anroid
