+ * The methods in this file offer a way to pass in the required
+ * JNI instances in the cubeb library. By default they return NULL.
+ * In this case part of the cubeb API that depends on JNI
+ * will return CUBEB_ERROR_NOT_SUPPORTED. Currently only one
+ * method depends on that:
+ *
+ * cubeb_stream_get_position()
+ *
+ * Users that want to use that cubeb API method must "override"
+ * the methods bellow to return a valid instance of JavaVM
+ * and application's Context object.
