Failed to write into slave jar cache

Issue Type:	Bug
Assignee:	Unassigned
Components:	remoting
Created:	2016/Jul/26 10:39 AM
Priority:	Major
Reporter:	Oliver Gondža

Slave got stuck in a state unable to load any classes/resources from master.

The jar was not written nor the C1 directory was created. I suspect the failure to create directory is silently ignored at https://github.com/jenkinsci/remoting/blob/3622f876e1b1f7548c9e7db0d4d09b76d80c87cc/src/main/java/hudson/remoting/FileSystemJarCache.java#L67
