Why do I see a BufferOverflowException when using NIO connectors?

Issue

• We have a problem using the org.apache.coyote.http11.Http11NioProtocol. Any client request that provides a Expect: 100-continue header fails to get a response and JBoss gives the following stack trace in the server.log:

ERROR [org.apache.catalina.connector] (http-localhost/127.0.0.1:8080-60) JBWEB001018: An exception or error occurred in the container during the request processing: java.nio.BufferOverflowException
