Steps to Reproduce

It's difficult to describes steps to reproduce it, because there is a lot of native code here.
I basically have a single activity with two bundles on it.
I'm using the class ReactInstanceManagerBuilder to create my bundles.

1. Create a simple activity
2. Instantiate a React Bundle
3. Get a RootView from the bundle
4. Inflate this RootView into the page
5. Instantiate another React Bundle
6. Get the RootView from the bundle
7. Inflate the RootView 2 into the page

Expected Behavior

Open two bundles in a single Android Activity.

Actual Behavior

It actually opens it. However, I have random crashes when the bundles tries to update its view props.

public void updateShadowNodeProp(
        ReactShadowNode nodeToUpdate,
        ReactStylesDiffMap props) {
      try {
        if (mIndex == null) {
          SHADOW_ARGS[0] = extractProperty(props);
          mSetter.invoke(nodeToUpdate, SHADOW_ARGS);
          Arrays.fill(SHADOW_ARGS, null);
        } else {
          SHADOW_GROUP_ARGS[0] = mIndex;
          SHADOW_GROUP_ARGS[1] = extractProperty(props);
          mSetter.invoke(nodeToUpdate, SHADOW_GROUP_ARGS);
          Arrays.fill(SHADOW_GROUP_ARGS, null);
        }
      } catch (Throwable t) {
        FLog.e(ViewManager.class, "Error while updating prop " + mPropName, t);
        throw new JSApplicationIllegalArgumentException("Error while updating property '" +
            mPropName + "' in shadow node of type: " + nodeToUpdate.getViewClass(), t);
      }
    }

This method throws many different exceptions.
