Re: System.getenv vs Ant 1.8.1's Execute

[Xavier Hanin <xa...@gmail.com>]

Hi,

I got no problem and no difference on my Mac:
----
env $ java -jar build/lib/ant-usertests.env-0.1-SNAPSHOT.jar
Detected OS_NAME: mac os x
Detected OS_ARCH: x86_64
Detected OS_VERSION: 10.5.8

Both methods returned the same environment information
env $ java -version
java version "1.6.0_17"
Java(TM) SE Runtime Environment (build 1.6.0_17-b04-248-9M3125)
Java HotSpot(TM) 64-Bit Server VM (build 14.3-b01-101, mixed mode)
----

Thank you for checking.  I forgot to say so but the same is true for

Maybe I should add this information to the output by default.
