Answering my own post. On the particular machine in question, I managed to
install rJava after installing
(in the OS) libbz2-dev and liblzma-dev. There was a hint of this in the install
output,
but not as clear as would help a novice.

Hi Martin,
Thanks for providing the reference.
In this particular case, it helped me to discover that 13 JVM threads
were garbage collecting in parallel, occasionally resulting in a race
condition. Setting
options(java.parameters = "-XS:ParallelGCThreads=1")
appears to resolve the issue
Thanks Jeff; indeed it works:
.jcall("java/lang/System", method = "gc")

Do you really, really need to run the garbage collector?

rJava offers a mechanism to call arbitrary methods in Java. Wouldn't you use
that mechanism to call whatever you would call if you were programming in Java

"What could be the reason" might be that you don't have 64bit Java runtime
installed. Either install that, or if you have 32bit Java runtime installed
then you could try running the 32 bit version of R.

My guess would be that your running the 32 bit version of R - and
rJava is looking for the 64 bit dll. I'd suggest starting the 64 bit
version of R explicitly (e.g. the 64 bit version of Rgui lives at
/bin/x64/Rgui.exe, whereas the 32 bit version lives at
/bin/i386/Rgui.exe).

Hello,
it seems that rJava tries to detect the path to the Java Virtual Maschine
from a registry key which is not installed. I gues that the HLM means
HKEY_LOCAL_MASCHINE where you find normally the path to your installed Java.
On my Windows System i have for example the path
HKEY_LOCAL_MASCHINE\S
sn't clear what this thing finds.
if you do something like "which -a java" and "which -a javac" you may see some
