[R-pkg-devel] Including a jar file in a package

We are developing a package that makes a call out to a Java program.  We 
have placed a jar file for this program in inst/java and it works 
nicely.  However, when we run R CMD check, it results in a NOTE:

* checking installed package size ... NOTE
   installed size is 11.0Mb
   sub-directories of 1Mb or more:
     java  10.8Mb

Is it likely that CRAN would accept a package that includes a large 
subdirectory like this?  If not, what is the recommended way to do 
this?  The nice thing about our current solution is that the user of our 
package does not need to separately install the Java program and deal 
with Java's classpath.

Thanks for the advice.
