Jenkins 1.606
Workflow 1.5
Take the following script as an example:
node {
def sleeps = [ : ]
for (int i = 0; i < 4; i++) {
sleeps["num_${i}"] = { sleep60() }
}
parallel(sleeps)
}
def sleep60 () {
ws {
stage name: "Sleep for 60 secs", concurrency: 1
sh "sleep 60"
}
}
Because the stages are marked with concurrency: 1, I would expect the sleeps to occur in series, but with all "parallel" tasks performed. With 3, then 2, then 1 task blocked until all are complete.
Instead the first sleep runs, the second blocks on it, but the other two mysteriously "fail", and this actually results in the Job hanging indefinitely and the 2nd sleep doesn't seem to get to run either.

I assume this is just a bug rather than my misunderstanding of the use of concurrency but I'm happy to be corrected!
