After some trial and error I figured out how to pass matrices from R to java and back using rJava, but this method is not documented and I wonder if there is a better way?

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.
