Dear R people, I have recently started using rJava to interact with Java code that I have written and am finding it a very useful bridge. Thanks! I have now run into a problem I can't figure out.

Hi All, I have written a Java MapReduce code that runs on Hadoop. My intention is to create an R package which will call the Java code and execute the job. Hence, I have written a similar R function.

I'm writing a package that successfully calls Java from R using rJava. When R sends my Java function bad data (through .jcall()), I get the error message details (when I run it on a console) and then: Java requested System.exit(1), closing R. Is there a way to call .jcall so that when Java receives bad data, the Java function will exit, but won't take down R with it? Thanks, Sigal

I also tried to use .jarray / .jcast in various combinations to no avail.

Now If if, create my own vm (see below), and then run .jinit (which will

Hi Dirk, It was unclear to me to which extent it is a kernel/security patch vs (r)Java issue. In any case, this is really problematic for me as it prevents me de facto from running some key R packages for my daily work. I'll post again if I see some solution (other than downgrading the kernel) somewhere. Meanwhile, any suggestions for a fix is welcome. Cheers Lorenzo On Mon, Jun 26, 2017
