new AndroidJavaObject hanging only on certain devices.

Hello folks,

We're using Unity's LVL checker that they've included in the Asset Store to check if the app has a valid licence.

In it is the code

 var dcl = new AndroidJavaObject("dalvik.system.DexClassLoader",
                                         cachePath + "/classes.jar",
                                         cachePath + "/odex",
                                         null,
                                         m_activity.Call<AndroidJavaObject>("getClassLoader"));

Now this piece of code works fine on most devices. However, we have a Samsung Galaxy Tab 10.1 with O.S version 3.1 and on this device the above code just hangs. It never returns, which obviously causes the app to hang.

I really have no idea why this happens on this device, any ideas or suggestion... anything at all?
