Ciao,
utilizzo vaadin 7.7.9 su IBM Portal 8.5.5.11.
Purtroppo riscontro diversi problemi nella comunicazione con il BE (RC: 104 connection reset e RC:107 Transport endpoint is not connected), questi eventi arrivano a mandare in hung i thread del webContainer.
Lo stacktrace tipico è:
ThreadMonitor W CWWSR0605W: Thread “WebContainer : 4941” (00022a1f) has been active for 668379 milliseconds and may be hung. There is/are 70 thread(s) in total in the server that may be hung.

ho trovato queste segnalazioni:
https://github.com/vaadin/framework/issues/3693
https://github.com/vaadin/framework/issues/6943
https://github.com/vaadin/framework/issues/5558
https://vaadin.com/forum/thread/10447917
ma nella 7.7.9 che ho dovrebbero essere già comprese le fix per le casistiche sollevate, avete esperienza in merito? O avete notizia di regressioni nella versione di framework che utilizzo?
grazie
