[BioC] intern=TRUE seems not working in system command in Mac OS

[rcaloger]

Hi,
I am trying to save the output produced from the following command in Mac :

 > tmp.java <- system("java -version", intern=TRUE)
java version "1.6.0_29"
Java(TM) SE Runtime Environment (build 1.6.0_29-b11-402-11M3527)
Java HotSpot(TM) 64-Bit Server VM (build 20.4-b02-402, mixed mode)
 > tmp.java
character(0)

The intern command work perfectly under windows and linux .
Is there any other option to get manage to save the output of system 
command in a variable?

Cheers
Raffaele
