The JVM would be initialized when xlsx is loaded or when certain
functions in the package are called depending on how the package was
written so as long as you set the java.parameters option prior to
issuing the library(xlsx) command you should be ok.  If that does not
work and assuming the number I suggested is big enough then it must be
something else.  You could try contacting the author to see if other
users have experienced this.

If you still can't get it to work there are a number of alternatives
listed here:
