---------------------------------------
Summary: Unable to use DynamicPortForwarding + LocalPortForwarding
Key: SSHD-1033
URL: https://issues.apache.org/jira/browse/SSHD-1033
Project: MINA SSHD
Issue Type: Bug
Affects Versions: 2.5.1
Reporter: Guillermo Grandes
This is the error running LocalForwarder + DynamicForwarder:
{code:none}
[sshd-SshClient[457e2f02]-nio2-thread-6] WARN

{code}
This is the code to reproduce.
* When testLocal = true, testDynamic = true; dynamic fail.
* if the order of test are inverted, fail the local instead of dynamic.
* if one test is false, the other works well.
