[jira] [Commented] (BEAM-14250) Coder registration doesn't work for types in main module.

    [ https://issues.apache.org/jira/browse/BEAM-14250?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17517168#comment-17517168 ] 

Robert Bradshaw commented on BEAM-14250:
----------------------------------------

> This is because type equality is not preserved through pickling. (Similarly for any other dynamic types that can't be pickled by reference.)
