SSH Agent Plugin - Infinite Thread - Thread Hangs - Thread stuck
Issue Type:
Bug
Affects Versions:
current
Assignee:
Unassigned
Components:
ssh-agent
Created:

Description:
For every build, SSH Client plugin create a thread that never ends.
It seems to come from this class :
com/cloudbees/jenkins/plugins/sshagent/jna/AgentServer.java
AgentServer.java
thread = new Thread() {
public void run() {
try {
while (!stopped) {
final UnixSocketChannel clientSock = channel.accept();
clientSock.configureBlocking(true);
new SshAgentSession(clientSock, agent);
}
} catch (Exception e) {
if (!stopped) {
e.printStackTrace();
}
}
}
};
I do not really understand the while loop necessity here. The thread will hang in the "channel.accept()" method only the second time it passes in.
Here is the stack :
