I was not able to run any R package which depended on rJava, which in binary form was provided by r-cran-rjava. The issue was that after the update the already installed R packages which were depending on rJava were not able to load. So build-depend would not have helped me, because I was not building any packages. Everything started to work after install of default-jre. Since I did not try to reproduce the bug on a clean install, there is a chance that my problem was self-inflicted, i.e. my admin did something not entirely advisable. I think we can close this issue. I’ve reported the issue, solicited the reaction and reaffirmed “java is tricky” idiom, so everything is cool from my side.
