    This fix breaks AndroidJavaClass.
    Starting 2019.2.11 we get "AndroidJavaException: java.lang.NullPointerException: Attempt to invoke virtual method 'java.lang.String java.lang.Class.getName()' on a null object reference"

    with this code calling CallStatic:

    using (var pluginClass = new AndroidJavaClass("com.prime31.analytics.FlurryAnalytics"))
    {
    _plugin = pluginClass.CallStatic<AndroidJavaObject>("instance");
    }

    2019.2.10 works fine.

    This doesn't seem to be fixed for me in 2019.2.14

    Since 2019.2.11 we started experiencing this crash (when it should have been resolved actually), never had a problem before, crashes 100% of the time here:

    // find the plugin instance
    using( var pluginClass = new AndroidJavaClass( "com.prime31.EtceteraPlugin" ) )
    _plugin = pluginClass.CallStatic<AndroidJavaObject>( "instance" );

    Works fine with 2019.2.10 and below
