It's hard to imagine why this would happen. using `paste(errs,
collapse="")` vs. `paste(errs, collapse="\n")` will provide you with
one character vector/string, so I've got to believe the problem is
somewhere else.
Just a stab in the dark, but does `paste(errs, collapse="\\n")` give
you problems?
What if you take your `errs = paste(errs, collapse="\n")` and call
`writeLines` on `errs` to a tmp file that you provide the path for to
rJython, which then reads the file and append into a message.
Also -- if you want to be reading the file "normally" on windows,
shouldn't you be using windows line endings (I think "\r\n"), or does
outlook recognize "\n" as a new line (I'm imagining if you do get the
whole thing to work, outlook might still just show you one long line
since "\n" alone isn't recognized as a newline command on windows
(last time I checked)).
