What steps will reproduce the problem?
 I do not have access to source code, but the project worked fine with GSON 1.71 but this regression is observed in GSON 2.1.

What is the expected output? What do you see instead?
 Normally generated JSON structure.

What version of the product are you using? On what operating system?
GSON 2.1 on Windows 7, replacing with older GSON 1.71 eliminate the problem.


Please provide any additional information below.
Unfortunatelly full stack trace impossible to get, due stack overflow, here is

I got this issue too, but it worked fine until I upgraded to the latest JDK 
1.7u4, so I guess it will soon be a problem for many developers.

I got it with u3. Interesting if the problem is really GSON or JDK.

Very interesting. Could you share what type you were serializing? I'd love to 
get to the bottom of this.

I too got the same exception when loading the java objects from json file. I 
have registered JsonDeserializer adapter for polymorphic classes.
I could not start the application as the startup servlet need to parse and load 
the configured objects in the json file.

There isn't much I can do about this until we know which type was being 
serialized.

class TestClass { Thread t; }

Although no json interpretation could be expected, a more graceful error would 
be nice.

This bug reproduces with this test:

  static class ToResolve<T> {
    List<T> list;

    public void testResolve() throws Exception {
      System.out.println($Gson$Types.resolve(new TypeToken<ToResolve<? extends T>>() {}.getType(), ToResolve.class, 
          ToResolve.class.getDeclaredField("list").getGenericType()));
    }
  }

  public void testResolve() throws Exception {
    new ToResolve<Void>().testResolve();
  }


It will also reproduce with Guice by using a TypeLiteral instead of a TypeToken.
      System.out.println(new TypeLiteral<ToResolve<? extends T>>() {}
          .resolve(ToResolve.class.getDeclaredField("list").getGenericType()));

I've been staring at this for a while and I'm starting to think it's a 
programming error. When this situation comes up, the runtime types are a hall 
of mirrors!

Outermost we have our declaring class: ToResolve<T>.
It creates a ToResolve<? extends T>, so its T is defined as ? extends T.
That wildcard is resolved to <? extends ? extends ? extends ? extends ... T>, 
never reaching a definite type.

We could try to naively defend against this, but we'd still be broken for many 
cases. There's an arbitrary number of ways to make a type recurse onto itself.
  ToResolve<? super List<T>>

We could keep an explicit stack, and if we ever attempt to resolve a type 
that's already on the stack, we've entered an illegal recursion and could 
terminate immediately without resolution. This is unsatisfying but it would 
work.

I think the right solution is for impacted apps to rethink their models. Why 
are they serializing types that are not well-defined? Why are they serializing 
'Thread' objects without a type adapter? Is this just capturing a lot of 
information for debugging? That's a bad idea, particularly since circular 
references are also possible.

I'm willing to hear genuine use cases here, but I think the solution is going 
to be to forbid this case and leave the stack overflow as-is.

The problem I encountered was : 
 * same stack trace
 * able to reproduce, again and again.
 * able to debug,
 * origin of troubles : the serializer wasn't registered for the real type of the object (using registerTypeAdapter) but for a mother class of it (found it through debug).
 * explaination of what happened in my case : the Gson object found by itself acceptable adapter for the real object, but stumbled upon deep hidden object java.lang.ref.ReferenceQueue which had a member pointing to the object itself, hence the stackoverflow, as the serializer looped over it.

 * correction : added a-bit-crappy command  : 
 gsonBuilder.registerTypeAdapter(objectToSerialize.getClass(), // to get its real type
 objectToSerializeSerializer);
(as the real type class of the object to serialize is private).

I have same problem when using API 17.
On smaller API versions it's all OK.
Why on API 17 - i got StackOverflow error?

I believe it was in API 17 that the internals of WeakReference and 
SoftReference changed to be self-referent, which would trigger this. Are you 
using Gson to serialize a WeakReference or SoftReference? If you are, you 
should write your own TypeAdapter for those types.

I am seeing this issue as well, and only on API 17.  API 16 and lower work 
fine.

Here is my case, I have this JSON response that I want to convert to a java 
object, with GSON v1.7.1 it works just fine, while with 2.2.2 it fails with the 
StackOverflow error on Android API 17, what am I doing wrong?

The problem is classes like SoftReference and WeakReference. Are you 
serializing either of those? (Because those classes have self-referential 
generics.)

No, I don't have the classes serialized, and there are no self referential, the 
main class has 2 sub types, which are just simple pojo 1 level String or int 
types..

No SoftReference or WeakReferences in our code either. Very basic classes that 
work on Android 4.1.2 and don't on 4.2.x. Not a Java expert and am unclear on 
how, if this is an internals issue, gson v1.71 resolves the issue? Thanks.

Dan: it's a problem with types that circularly reference themselves. It's most 
notable in WeakReference & SoftReference, which started to circularly reference 
themselves starting with Android API 17.

I'm reopening this because the app developer can't do much to defend himself 
against this, and it's an ugly crash.

I am having the same issue for API 15 as well. Worked fine on API 8.

In .NET, you are not allowed to serialize/deserialize complexe objects that 
might recur into itself. Runtime exception is thrown when 
serialization/deserialization of such objects are attempted.

IMO, you should disallow this use case. Or specify a max recursion level to 
serialize/deserialize into.

This turn out to be the declaration of android.os.Handler in the

In case this help narrow the problem, I solved the problem by following Zar 
answer on http://stackoverflow.com/a/14572063/279565.

I had added at some point a member
private LogCentral log = LogCentral.getInstance();

LogCentral being a singleton, (not related to Log4j or smilar). Just a plain 
simple filewriter class.

Making the member static solves the problem, although I don't know why.

this bug is reproducable with this simple class
public class Prepare {

    private ScheduledThreadPoolExecutor downloadJobExecutorPool;
    public static void main(String... arguments) throws Exception  {
        Prepare stService = new Prepare();
        System.out.println(stService.toJson());
    }
    public String toJson(){
        Gson gson = new Gson();
        return gson.toJson(this);
    }

}

have a ScheduledThreadPoolExecutor in your class and this bug happens in 2.2.2 
and 2.2.4 but not in 1.7.1

I reproduced this error in the following use case: I have a series of objects 
that use a generic fluent pattern, i.e.

    public MyAbstractClass<M extends MyAbstractClass> {
        private int value;
        public M setValue(int value) {
            this.value = value;
            return (M) this;
        }
    }

    public MyImpl extends MyAbstractClass<MyImpl> {
        private int foo;
        public MyImpl setSomethingElse(int foo) {
            this.foo = foo;
        }
    }

    public static void main(String... args) {
        MyImpl impl = new MyImpl();
        myImpl.setValue(1)
              .setSomethingElse(foo);
    }

I'm not really griping that this error happens so much as:

1) It's difficult to diagnose exactly where the problem is
2) The object that I was serializing had a registered type adapter for it's 
INTERFACE, like:

    public MyOuterClass implements SomeInterface {
        private MyImpl impl;
        // etc.
    }

then:

    gsonBuilder.registerTypeAdapter(SomeInterface.class, someInterfaceTypeAdapter);

Where someInterfaceTypeAdapter doesn't call anything on the MyImpl argument. 
What I'm saying is, it shouldn't have this hangup when there's a type adapter 
that's supposed to handle the job. I fixed the problem by doing:

    gsonBuilder.registerTypeAdapter(MyOuterClass.class, someInterfaceTypeAdapter);

Gson should be smart enough to realize it doesn't have to go through the 
trouble of reading all the fields if there is an appropriate type adapter.

 on Version 2.2.3
I have same issue cause my model implements Comparable of its type:
 class X implements Comparable<X>{
 // members ...

 // @NOTE: this has a problem when down grading to 1.7.1
 Map<String, Object> parameters;

}

when I downgraded to version 1.7.1 the parameters map is not deserialized 
correctly if I received a String for the value, this will save the key 
correctly but the String value is saved as object and when trying to cast it 
back to string It will throw an exception.

I had the same problem. Turned out that my model classes parent class had a

Same issue here with Objects containing WeakReferences. Because I didn't need 
that particular ivar to be serialized, I circumvented this problem by applying 
the transient flag.

Hope this will help save others some debugging time: in my case it was caused by a field of non-serializable type (Thread), and solved by marking it as transient.
