Prior to upgrading from 1.510 to 1.533 the CoypToSlave (version 1.3 I think) was working without any errors. After upgrading to Jenkins 1.533 the plugin would fail with a "Pipe already closed" exception.

I cloned the git repository from https://github.com/jenkinsci/copy-to-slave-plugin and attempted to debug/fix what I believed was a double close error. I have a working branch where I'm no longer getting a double close error but an exception caused by "Unexpected end of ZLIB input stream" AFTER all the files have been copied to the remote. My current working branch ignores the failure as a short term fix for my environment.

My working code can be found at:

https://github.com/cmdrclueless/copy-to-slave-plugin/tree/pipe_already_closed

The current exception stack track follows:
