Sometime our customers have network problems (e.g connection interrupted for a short period) and if that happens when we are sending response for a page, an exception is thrown:
*2020-04-23 18:47:28 ERROR [ba00c0b5f1c83a39/ba00c0b5f1c83a39] [00529169] [m00080874] DefaultExceptionMapper:144 - Connection lost, give up responding.org.apache.wicket.protocol.http.servlet.ResponseIOException: org.eclipse.jetty.io.EofException* which is normal. But after that if a user tries to do something else in the same page (e.g clicks on an Ajax Link) a deserialization error appears (like stack trace below). Did anybody else encounter the same behaviour? We are using Wicket 7.10.0 and do not understand: 1. why serialized page contains information (details of connection exception) when serialized 2. why EofException is not found during deserialization, since it was thrown seconds before in the same running JVM ======================================================== 2020-04-23 18:49:51 ERROR [850aa812ac5fa019/850aa812ac5fa019] [00529169] [m00080874]
