When we are closing the deepstream client on Android 8.1.1 version Application crashing.

Note: When the device is going to Offline, above crash is happening. This is only for Android Oreo and up.

I am also facing exact same issue on Android Oreo on MI A1.

Is there any workaround for this issue?

We need to upgrade Java-WebSocket:1.3.5 to Java-WebSocket:1.3.8. This issue is not coming from deepstream. It is coming from Java-WebSocket library. After upgraded Java-WebSocket:1.3.8, it was worked. We should wait to deepstream for upgrade the library. Otherwise we can do ourselves.

I updated the client from 1.3.5 to 1.3.8
It resolved Android Crash but something else breaking now.

Following exceptions occurred on devices:
