rJava Broken on Linux + R 3.4
Dear All,
I think there is something wrong with rJava on any Debian based
distribution.
I may be wrong, but I experiencing exactly the problems mentioned at
https://github.com/amattioc/SDMX/issues/130
and at
https://github.com/s-u/rJava/issues/110
A couple of packages (RJSDMX and xlsx) are now impossible to install
on my debian stretch platform running R 3.4.
It seems I am not the only one

rJava Broken on Linux + R 3.4
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

It is a Java issue related to a security fix many (most? all?) distros

problem using rJava with parallel::mclapply
Dear all,
I got an issue trying to parse excel files in parallel using XLConnect, the
process hangs forever.
Martin Studer, the maintainer of XLConnect kindly investigated the issue,
identified rJava as a possible cause of the problem:
This does not work (hangs):

RJava question(class not found with rJava's vm, though found with alternate vm)

.jclassPath, i can see the jar file containing the class. Yet when trying to
instantaite the class, i get a class not found error.

rJava and matrices
Hi list,
I'm wanting to use a matrix as input to some java code, but I seem to be
unable to do this (See code below). When searching online for a solution I
found that rJava 0.5-2 (the version under development not yet in CRAN) is
adding "direct support for raw vectors as method parameters". Is this
related?
I also tried to use .jarray / .jcast in various combinations to no avail.

Problems with xlsx and rjava
Hi,
I keep getting the below error regarding rJava which is required by package xlsx (I have used it in the past to directly import data from Excel 2010).
I was on R version 2.15.0 when I was getting this error this morning. So I upgraded to 2.15.1 but still the same problem. I tried unstalling and reinstalling xlsx and even rJava directly from the source as indicated here:

ClassNotFoundException when running distributed job using rJava package
Hi,
I have a MapReduce Java code, which I am calling from R using rJava. I have
prepared the R package and tested that successfully. But when I deployed
the package in a cluster and executed it, I am getting
ClassNotFoundException. If I run the same job directly without integrating
with R, it runs perfectly.
Here is my R code:

conflict between rJava and data.table
Dear devel-listers,
I found a conflct between rJava and data.table. Actually me questions is where to report it?
Should I rather send it directly to the package maintainers or post it on some bug tracker.
The problem is that data.table has a function called "J" and rJava uses the same quite intensively.
I used the xlsx R package which depends on rJava to write .xls files and ran
