R tells you your Java setup is not right. This *is* difficult, which is why I
have offered to maintain and provide the rJava in Debian / Ubuntu as r-cran-rjava.

As demonstrated to you two emails ago, it also works.  I would use that.
Otherwise, fix your Java setup first as R told you to here.

As before: not a bug in R and you just created extra work for R Core to
maintain the bug database.
