Location reuses feature object

[tobrun]

We have a raise condition on the location component feature. Currently we reuse the features object and pass that to gl-native. gl-native however parses this asynchronous and by that time we could already have updated it on the main thread. This currently results in a crash and is something we want to patch.

The feature object mentioned can be found in

mapbox-gl-native-android/MapboxGLAndroidSDK/src/main/java/com/mapbox/mapboxsdk/location/SymbolLocationLayerRenderer.java

Line 69 in 3467eef

private Feature locationFeature;
