scilab won't start unless symlink is placed

Reported by Ricardo Fabbri

BUG DESCRIPTION:
----------------
Scilab won't start on OSX mavericks, neither the binary version for the nightly build, nor the one compiled from source (neither with java 6 or 7)

ERROR LOG:
----------

Error checking symlink for the target jvm

HOW TO REPRODUCE THE BUG:
-------------------------
./scilab

or just double clicking on a scilab icon


OTHER INFORMATION:
------------------

Workaround: to place symlink to 1.5 as

Ricardos-MacBook-Pro-3:~ root# cd  /System/Library/Frameworks/JavaVM.framework/Versions/   
Ricardos-MacBook-Pro-3:Versions root# ln -s Current 1.5

Now everything works. I discovered that by printing debug info where the error log message above is printed in the code.
