Having investigated the issue, I discovered that the reason behind it is that the client completes its service deployment future at the wrong moment - it does so on receiving cache update event, and it could hardly be correct. As I see it now, the client rather should wait for a different event and probably listen for different cache that would store service deployment statuses. After having discussed it with Semen, it's currently unclear how to fix this without major rehaul which in turn could threat with future compatibility  issues (in cases when nodes of different Ignite versions live in the same cluster).
Anyway, the properly written test for this issue is in ignite-3392 branch.

> Test that demonstrates the issue is attached. If exception is thrown from the {{Service.init()}} method, it's only printed out on the server not propagated to the client. If client then tries to get the proxy, it goes to infinite loop.
