FYI using a t_SalesforceConnection component the following warning is thrown:

Thanks for raising this. TOS versions are not patched (and this may have been fixed in v8....I certainly haven't seen it so far). So that I can test to see if this still exists in v8, can you give me an idea of exactly what you did to get this? A screenshot of your job should suffice.

Thanks for getting back to me. I have checked this out. This is not an issue right now, but is a warning about a future change in Java.

"WARNING: All illegal access operations will be denied in a future release"

This will be amended before it is blocked in future versions of Java. In the meantime, it is safe to use.
