Description

We added the LongPolling transport to the Java client in https://github.com/aspnet/AspNetCore/pull/6856

But it currently doesn't do fallback, so the client either connects with the selected transport or it doesn't.

Contributor guide

Research direction
Understand the current LongPolling transport implementation in the Java client and implement fallback logic to try other transports if LongPolling fails.
