["Yannick Lecaillez (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/DIRMINA-774?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Yannick Lecaillez updated DIRMINA-774:
--------------------------------------

    Priority: Trivial  (was: Major)

Please ignore this bug report, was a mistake.

For the full story, i had problem with session.write() in a multi-threaded environment which caused invalid compressed data.
All worked like a charm as soon as i added an OrderedThreadExecutorFilter in the filter chain.

Sorry for the inconvenience.
