executing library('RJDBC') on R console shows java 6 installation message

Question

I'm trying to access a mysql database through R console using RJDBC in a mac os X system, but R console crash just after type in " > library('RJDBC') ". Immediately shows up a message indicating is necessary install the old Java 6 mac os version.

I already installed the package typing " > install.packages('RJDBC', dependencies=TRUE) "

My system have: OSX = Mac Os X (Yosemite) R version 3.1.2 (2014-10-31) java 7 installed and set JAVA_HOME env variable in my ./bash_profile file.

echo $JAVA_HOME
/Library/Java/JavaVirtualMachines/jdk1.7.0_60.jdk/Contents/Home

And also if it is useful

R CMD javareconf
Java interpreter : /Library/Java/JavaVirtualMachines/jdk1.7.0_60.jdk/Contents/Home/jre/bin/java

What Am I doing wrong? I even checked an old post how to get rJava 0.9-3 to work on OS X 10.7.4 with Oracle Java 1.7? and the http://mailman.rz.uni-augsburg.de/pipermail/stats-rosuda-devel/ but I haven't been able to make it work, Does anyone can help me?

Not sure if you figured this out yet, but you need to install Java for OS X 2014-001, which is found here...
