Jenkins started wrong slave for job restricted to specific one. Added test whether the currently checked slave computer actually can take the buildable item before flagging it as needed (avoids powering up and connecting to slaves for jobs they can't build).
When archiving artifacts, if the platform cannot read symlinks, fall back to visiting them as plain files or directories rather than failing the build. Also fixed a regression in untar on exotic platforms: fall back in non-JNA case wasn't working.
Security fixes (SECURITY-43, SECURITY-44, SECURITY-45).
Invalid JSON is produced during remote api operations when a changeSet contains duplicate keys.
Excessive memory usage with large number of request threads
