Exception thrown on multiple calls about linkedin-j HOT 5 OPEN

I'm having the same problem on Android. Using 0.1rc4 I receive an exception 
that is thrown on any subsequent calls that are after the first call to the API 
client.

Confirmed this issue also exists using the latest build (r310).

Looking at the oauth-signpost project 
(http://code.google.com/p/oauth-signpost/) I found:

"
Google Android
IMPORTANT: Do NOT use the DefaultOAuth* implementations on Android, since 
there's a bug in Android's java.net.HttpURLConnection that keeps it from 
working with some service providers. Instead, use the CommonsHttpOAuth* 
classes, since they are meant to be used with Apache Commons HTTP (that's what 
Android uses for HTTP anyway).

Signpost is already used in several applications running on Android, Google's 
software stack for mobile devices. In fact, Signpost has already signed 
thousands of HTTP requests at this very moment, as it is an integral part of 
Qype Radar, our geo-sensitive mobile application for Android that finds the 
best places near you.
"

I will try to change the library to avoid using the default OAuth 
consumer/provider.

I've managed to successfully replace the DefaultOAuth* consumer/provider with 
CommonstHttpOAuth* consumer/providers and have confirmed that it fixes the bug 
mentioned above for Android. Tested in Android 1.5, 1.6, 2.0 emulators as well 
as on a G1 running Android 1.5.

I could submit a patch containing my changes if you would like to integrate my 
fix. I essentially overrode the LinkedInApiClient callApiMethod() methods to 
provide methods that use the CommonsHttp classes.
