Re: [xmlvm-users] Examples for iphone-c target

I think the native methods are manageable. There are certainly a few but 
usually are easy to implement. I don't think we can leverage from the 
OpenJDK in this case; native methods are inherently dependent on the 
platform and we will need proper versions for iOS.
