Before posting this question, I have searched some other questions Rselenium remDR$open() error, RSelenium connect attempt produces Java error, Rselenium remDR$open() error, but none of these solutions could fix my issue. Since I don't have enough reputation to add comments under their solutions, so I have to post a new one. Forgive me if I do something fool in my first posing. Thank you. (I also reported the issue under the thread https://github.com/ropensci/RSelenium/issues/42, but still did not get the answer, sorry for my hurry)
The code I am about to run:
library(RSelenium)
unlink(system.file("bin", package = "RSelenium"), recursive = T)
checkForServer()
startServer()
remDr <- remoteDriver(browserName = "firefox")
remDr$open()
There are two different environments:
Ubuntu 14.04.3 LTS,
Mozilla Firefox 42.0,java version "1.8.0_66",
R version 3.2.2 (2015-08-14) -- "Fire Safety",
RSelenium 2.48.0"
OS X EI Captian version 10.11.1,
Mozilla Firefox 42.0,
java version "1.8.0_66",
R version 3.2.2 (2015-08-14) -- "Fire Safety",
RSelenium 2.48.0"
I constantly get the same error when running the code on Ubuntu, however, if I run the same code on Mac, everything works fine. Can you help me? Details are given as follows.

My blind guess: this could not be the version issue, otherwise, it cannot be run well on Mac, and both the versions of Firefox and RSelenium are the latest.
