[rhelv6-list] Java version

[Robert G. (Doc) Savage]

Just for fun, I'm trying to build binaries for Android 4.0.1 (Ice Cream
Sandwich) on my RHEL6.2 system (see
http://source.android.com/source/building-devices.html).

Early on I'm getting this error:

Checking build tools versions...
************************************************************
You are attempting to build with the incorrect version
of java.
 
Your version is: java version "1.6.0_22".
The correct version is: Java SE 1.6.
 
Please follow the machine setup instructions at
    http://source.android.com/source/download.html
************************************************************
build/core/main.mk:131: *** stop.  Stop.

Is this nit-picking? Is IcedTea6 really mainstream and usable, or is
this an exception and I need to download and install the genuine
article?
