This is a very weird issue as it looks like the string somehow gets trimmed from the beginning. No idea how this can happen.

We may need to look if this issue can occur again.

This is likely due to ComplexOptions.StaticProperty being a static property and shared with other tests that could be running at the same time, including another test that sets it to "stuff".
