| I would like to enquire about package r-cran-rjava on Debian jesse. It seems that if default-jre package is not installed, but openjdk-7-jre is installed, then library(rJava) in R fails. I?ve been bitten by this today and I wonder whether this an issue of mine, or is this a possible bug.

| My server admin used apt-get update and apt-get upgrade today and R started throwing an error that it cannot find libjvm.so, when trying to do library(rJava). At first I thought that this is a problem of setting JAVA_HOME, and setting it to JAVA_HOME=/usr/lib/jvm/java-7-openjdk-amd64 before starting R seemed to solve the problem. But this setting was ignored by shiny-server, so I spent some time figuring out how to force shiny-server to respect it. Only after repeated failure I?ve noticed that LD_LIBRARY_PATH in Sys.getenv() points to /usr/lib/jvm/default-java/jre/lib/amd64/server and there was no directory /usr/lib/jvm/default-java/ in the system. Then I found out that this library is provided by default-jre and when it was installed everything start to work. Then I investigated further and found that this package is only optional for r-cran-rjava. Hence the question.

You have the ?jre', you need the 'jdk'.
