[jira] [Resolved] (DIRMINA-1043) NullPointerException after upgrade
to mina 2.0.14
[ https://issues.apache.org/jira/browse/DIRMINA-1043?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Emmanuel Lecharny resolved DIRMINA-1043.
----------------------------------------
Resolution: Fixed
The NPE should be fixed : in specific cases, the WriteRequest future was null, leading to a NPE when doing things like :
{noformat}
writeRequest.getFuture().setWritten();
{noformat}
> NullPointerException after upgrade to mina 2.0.14

> Components: Core
> Affects Versions: 2.0.14

> After we upgraded to mina 2.0.14, we see a number of these exceptions. At this point we have not found a negative impact on our application but some important cleanup instructions may be skipped within mina.
