I have a stand-alone Java 1.7 application using Camel 2.14 and camel-netty which is running on Linux RHEL6.
For a route that consumes from *netty:udp* and also wireTaps to *netty:udp* on a remote server, I get lots of *java.nio.channels.ClosedChannelException* entries at ERROR level in my Camel *rootLog.txt*. >From googling, I see that this issue was discussed and worked for netty-http (i.e. * CAMEL-8289 <https://issues.apache.org/jira/browse/CAMEL-8289> *). My question is for *netty3:udp* is this still an issue, and would it be resolved by upgrading to *camel-netty4* and/or Java 1.8? Any thoughts on how I can prevent logging of these exceptions? Below is a sample entry from my Camel *rootLog.txt*?
