FixCRLF processing in assembly plugin sometimes fails under windows trying to rename a temp file

Assembly fails on windows. This was working for me for days and suddenly started giving me trouble.

C:\dev\asf\geronimo\branches\1.0\assemblies\j2ee-jetty-server> maven -o -Dgeronimo.assembly.zip=true -Dgeronimo.assembly.tar=true

<SNIP>

assemble:package-assembly:
[echo] Preparing CRLF line endings in text based files for zip
distribution
[zip] Building zip: C:\dev\asf\geronimo\branches\1.0\assemblies\j2ee-jetty-server\target\geronimo-jetty-j2ee-1.0.zip
[echo] Preparing LF line endings in text based files for tar.gz distribution

Running maven with -X we I see:
