Description

we are getting the following exception when trying to use more than two netty endpoints in a single route.

java.lang.IllegalStateException: await*() in I/O thread causes a dead lock or sudden performance drop. Use addListener() instead or call await*() from a different thread.

Sample route :

from("netty:tcp://localhost:7000textline=true") .bean(DummyProcessor.class)
.to("netty:tcp://localhost:7001?textline=true") .bean(DummyProcessor.class)
.to("netty:tcp://localhost:7002?textline=true")
.bean(DummyProcessor.class)
.to("netty:tcp://localhost:7003?textline=true")
.bean(DummyProcessor.class)
.to("netty:tcp://localhost:7004?textline=true")
.bean(DummyProcessor.class);

camel version : 2.11
netty 3.6.5

The same is working in 2.10.3 version.
