[jira] [Comment Edited] (DIRMINA-1120) ProtocolCodecFilter does not
support concurrent access
[ https://issues.apache.org/jira/browse/DIRMINA-1120?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17013955#comment-17013955 ]

It's true I should make sure that the filters I'm using are thread-safe and I found the ProtocolCodecFilter was thread-safe before version 2.1.1 but some new designs are broken since v2.1.1. The same write request object is passed to the next filter with different messages in queue by mistake in the filterWrite method. It makes the previous messages might be overwritten by next messages and the next messages' buffer might be used up when they come to the IoProcessor again.
