--------------------------------------
Summary: SshException MAC Error in
org.apache.sshd.common.session.AbstractSession.decode when using
Nio2ServiceFactory
Key: SSHD-252
URL: https://issues.apache.org/jira/browse/SSHD-252
Project: MINA SSHD
Issue Type: Bug
Affects Versions: 0.9.0
Reporter: Michael Heemskerk
I've been running an extended version of the {{LoadTest.testLoad()}} test to
verify a performance improvement I'm working on. While running these tests,
I've noticed that the test fails occasionally, but only when using the
{{NioServiceFactory}}.
The following error is logged:

I've reproduced these failures against an _unmodified_ 0.9.0 version with the
