Ok, I try to explain the problem better:

getHome() uses now "GetModuleFileName()" to determine
the R home-directory. "GetModuleFileName()" doesn't check
the R_HOME environment setting, instead it returns the
path of the .EXE, that started R, which is usually located in
$R_HOME/bin. If R is invoked via Java, "GetModuleFileName()"
returns $JDK_HOME/jre/bin instead of $R_HOME/bin and
the function "getRHome()" returns $JDK_HOME/jre...

My suggestion is just to rely on $R_HOME, instead of
using "GetModuleFileName()", because all "xxx calls R"
packages will have similar problems. I added in my sample
fix the check for $RHOME, since SJava does the same,
may be this is historical, just ignore it...
