Does Jenkins on Windows handle processes and file handles differently?

I have an Ant target invoked by a build that writes its output to a log file but that target also happens to do a <move> on that same file (I know, I know...) while running. I'm getting an "unable to delete" warning, which makes sense, but it stops the rest of the move operation, which is a huge problem.

BUT this always worked without a problem in CruiseControl on the same Windows 2008 R2 machine. In fact, this Ant target has always worked on Windows machines always. This build also works on our Jenkins-on-Linux machines as well. Just not on Jenkins-on-Windows.

I'm baffled. Is there something that jenkins.exe is doing that causes file handles to be treated different by child processes? Am I going completely insane?

Latest Jenkins on jdk1.8u66, same jdk for Ant

No exotic plugins, this part of the build in question is invoked in the vanilla Jenkins "Execute Windows Batch"
