Please ignore the first comment.
The actual bug description is here :
Following problem was discovered using JSCH to access Ubuntu guests on system z
remotely. Using "exec" based channel with JSCH, every once in a while we get
back an empty string as output to a command that should return output.
For example "which mkdir".
The results are random and this can happen on any command.
I was not able to reproduce without JSCH.
I conducted a simple test, running the "echo offer" command 400 times.
in average it will return an empty string 4 times out of the 400 tries.
The usage of JSCH, which is required is the blocking problem of major
test scenarios of a product.
this is how the JSCH channel looks like:
Channel channel = session.openChannel("exec");
((ChannelExec) channel).setPty(true);
((ChannelExec) channel).setPtyType("dumb");
((ChannelExec) channel).setCommand(command);
connOut = channel.getOutputStream();
connIn = channel.getInputStream();
connErr = ((ChannelExec) channel).getErrStream();
channel.connect();
JSCH version used is jsch-0.1.53.
yet this does not seem to be a JSCH problem.
