[1.429] fix for JENKINS-8856 seems to break perforce plugin
Felix Drueke
after updating from 1.428 to 1.429 or 1.430 I experienced issues with
the perforce plugin on some remote nodes.
The plugin can't seem to read the output of the "p4" executable.
Errors look like this:

Or similar.
I debugged the problem and found that jenkins is waiting forever in method:
com.tek42.perforce.parse.AbstractPerforceTemplate.getPerforceResponse(String[] cmd, ResponseFilter filter)
when trying to read from the BufferedReader
This is the line:
https://github.com/jenkinsci/perforce-plugin/blob/master/src/main/java/com/tek42/perforce/parse/AbstractPerforceTemplate.java#L330
I suspect the problem is the fix for https://issues.jenkins-ci.org/browse/JENKINS-8856
which dups stdin/out on OS-level.
Best regards,
Felix

Can you please file an issue for this on issues.jenkins-ci.org, and include as much detail as possible? We'll need things like master and slave Os and java versions.
Thanks!
