[jira] [Commented] (MPOM-204) Getting INSTANCE error while running maven build using POM

    [ https://issues.apache.org/jira/browse/MPOM-204?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16562145#comment-16562145 ] 

Robert Scholte commented on MPOM-204:
-------------------------------------

This means that you're using a different version of {{org.apache.http.conn.ssl.SSLConnectionSocketFactory}} then originally used by {{HttpWebConnection}}.
Maybe you have multiple versions of SSLConnectionSocketFactory on your classpath, or an older/newer version of the dependency containing this class (probably http-client).
