Issue inside tomcat container.

I am trying to setup APNS client while starting the container inside ServletContextListner. I am getting following exception. This same certificate and code is working locally.

 java.nio.channels.ClosedChannelException

Any help? The jars I am using are: alpn-boot-8.1.6.v20151105.jar and alpn-api-1.1.2.v20150522.jar with tomcat 8

[Jon Chambers]

Well, according to the docs, an `IllegalAccessError` is:

> Thrown if an application attempts to access or modify a field, or to call a method that it does not have access to.

That may indicate that you have a mismatch between your alpn-boot version and the JDK you're running. Are the JDK versions different between your local and server environments?
