We are having a build that fails when passed this build selector parameter:
<SpecificBuildSelector plugin="copyartifact@1.26"> <buildNumber>2</buildNumber></SpecificBuildSelector>
like so:
Unable to find a build for artifact copy from: 7.2patch211_integrated-installer_patch

Yet passes with a parameter like this:
<StatusBuildSelector plugin="copyartifact@1.26"/>
like so:
Copied 17 artifacts from "7.2patch211_integrated-installer_patch" build number 2

The failures only occur for us on slaves version >2.20. Slaves with version 2.20 have been verified to work, while we have seen version 2.22 and 2.23 fail.
