JSApplicationIllegalArgumentException with Android

Recently, we integrated the reaction in native into our application with just a simple textual representation. We get this crash on all devices.

We show plain text with React Native.

'use strict';

import React from 'react';
import {
  AppRegistry,
  StyleSheet,
  Text,
  View
} from 'react-native';

class HelloWorld extends React.Component {
  render() {
    return (
      <Text style={{color: 'white'}}>React Native is running</Text>
    )
  }
}

AppRegistry.registerComponent('8fit', () => HelloWorld);

We use React Native 0.35.0-rc.0, but we also got the same crash with a stable release 0.33.1.

Here you can find the full crash report. https://gist.github.com/sealskej/1e2398ef1cd9dda2d1b2630348fa612a

Any help leading to a fix problem would be greatly appreciated!
