Hi,
I am copying Simon here, as he is the package author/maintainer for RJDBC.
Typically, segfault's can indicate some kind of version mismatch in the
components that have been installed.
Since there are multiple pieces to this installation, between the packages and
the underlying Java installation on your Mac, I would defer to Simon's more
intimate knowledge here.
In searching for related issues, I noted some other posts on multiple OSs, and
some issues raised on Simon's Github repo for the package.
Also, I am torn between suggesting that this be re-posted to r-sig-db, which is
specific to R and database interfaces, and r-sig-mac, which is specific to R on
macOS.
However, I will defer to Simon on how he might prefer to handle follow up
discussion on your issue.
Regards,
Marc Schwartz
