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): library(parallel) require(rJava) .jinit() res <- mclapply(1:2, function(i) { J("java.lang.Runtime")$getRuntime()$gc() 1 }, mc.cores = 2) but this works: library(parallel) res <- mclapply(1:2, function(i) { require(rJava) .jinit() J("java.lang.Runtime")$getRuntime()$gc() 1 }, mc.cores = 2)...

Not sure if this the right place, but I can't seem to subscribe to the rJava mailing list. Sorry for the noise. I have a jar file in the CLASSPATH variable. On running .jinit and checking .jclassPath, i can see the jar file containing the class. Yet when trying to instantaite the class, i get a class not found error. Now If if, create my own vm (see below), and then run .jinit (which will use my vm), i can find the class in question (org.apache.hadoop.io.longwritable)...

Hello All, Although running Java from R used to work, for some mysterious reason, it's stopped.

Using Java at "" instead. - JavaVM: Failed to load JVM: /bundle/Libraries/libserver.dylib - JavaVM FATAL: Failed to load the jvm library.

.../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 experiencing this and it may be due to some security patches just released. However, if I run on my machine > library(rJava) > .jinit() I get a segmentation fault, though I was able to install rJava, it does not seem to work properly. Does anyone have a fix for that? Many thanks Lorenzo
