Thanks for the patch and the test cases!

If the 'OverwriteReadOnlyFiles' property is not set (default false?), then we should probably not be copying the file at all and log it. In case of multiple files, the Copy task logs an error and continues with remaining files. Same should be done in this case. And the test would need to be updated for that. What does msbuild do ?
