We had an issue whereby there were a set of changes which were submitted but not yet accepted into MKS Source. Some of the changes involved new source files (JUnit tests in this case), and others involved changes to existing files.

What I am seeing is that regarding changes to existing files, the plugin correctly does not download them until the change package is eventually accepted. However for any new files, this isn't the case - it downloads the immediately no matter what the status of the change package.

In our case the new JUnit tests were being automatically run even though the corresponding changes had not yet been applied and it caused the build to fail.
