Chuck Burgess commented on STORM-1193:
--------------------------------------
This probably has something to do with this --
http://superuser.com/questions/104845/permission-to-make-symbolic-links-in-windows-7
If the running user is in the Administrators group, then that seems to trump
the user account itself being granted the Create Symbolic Links permission.

> Reporter: Chuck Burgess
> Priority: Minor
>
> The test-worker-launch-command-run-as-user testcase errors rather than fails,
> due to what seems to be a privilege issue with creating a symlink.

> I don't know if the testcase itself should be catching the error and
> presenting it as a failed test, or if the original code should be catching it
> and reacting.
> What's odd here is that if this is using my own user account and privileges,
> then it should work, because my account _does_ have permission to create
> symlinks.
> Tested against master branch (c12e28c829)
