Is singleton of XMPPTCPConnection possibly bottleneck?

[onacit]

Hi. I already found that XMPPTCPConnections are thread-safe.

Is XMPPTCPConnection thread-safe?

Can I create a XMPPTCPConnection by providing an instance of XMPPTCPConnectionConfiguration and share it across my threads? Or should I create connection per thread?

And I also found this page.

Threads and Executors

My application which is based on the Spring Boot uses a single XMPPTCPConnection which is initialized at boot time.
That means event HTTP request uses the singleton instance to talk to the Openfire.

My question is.

Is it possibly bottleneck? How many threads can it use?

Unlikely, and there is no thread limit.
