IllegalArgumentException: No matching constant for [-1] after upgrading from M4 to RC

[bjorntj]

I just upgraded from Spring for Android 1.0.0 M4 to RC1 and now I am gettting the following exception when trying to call my rest service the second time (first call works ok..):

java.lang.IllegalArgumentException: No matching constant for [-1]

What am I missing?

Ok, if I use HttpComponentsClientHttpRequestFactory instead of the default SimpleClientHttpRequestFactory then it works.... Does this mean the default should not be used or?

Hi, on which version of Android are you testing or running? It sounds like you reusing the same RestTemplate object when you make a "second request", is that correct? Any more details would be appreciated. As a workaround you can certainly use the HttpComponents client. Thanks!

[bjorntj]

I was testing under Android 3.2...
Also I thought about reusing the RestTemplate and now I became a bit unsure... I was certain I didn't reuse the RestTemplate but now I have to check again...

Btw, what are the pros and cons of using the HttpComponent vs SimpleClient?

You should be able to reuse a RestTemplate object to make multiple requests. Google recommends using the standard J2SE facilities in Gingerbread and newer because of functionality improvements and bug fixes. In the RC1 release, Spring for Android now defaults to this in Gingerbread and newer. Here is a some additional information from Google:

So, any explanation to why I get IllegalArgumentException?

[Roy Clarkson]

It looks like the response is empty from the second request, and the default http status of -1 is not valid, which is the IllegalArgumentException. HttpStatus.valueOf() is expecting a valid http status, such as 200, for example. This can happen if there is an error when making the request, which is what looks like happened in the stack trace you provided.

I would like to investigate your scenario. Any additional details would be helpful. If I understand correctly, you are reusing a RestTemplate instance to make multiple requests on Android 3.2. The HttpComponents client works, but the Simple client does not. I'll start with that.

[bjorntj]

I don't think that I am reusing RestTemplate but I will double check at work tomorrow... But the rest is correct...
And yes, the error seems to occur before the request gets to the server...

Any more info you would like?

BTJ

[bjorntj]

No, I don't reuse my RestTemplate....

Ok, thanks. Can you provide the setup you are using when creating your request with RestTemplate? I don't need any proprietary information, but it would be helpful to know how you are configuring your request.
