Yeah - If you need to use an alternative VM instead of HotSpot, then 
IcedTea is an easier choice to start with.

In addition, in that case, I'd suggest starting with an older release 
rather than newer, i.e. 6/7/8, as the integration between alternative 
VMs and OpenJDK may take some time after a platform release so solidify, 
and have the support for new VM or class library features implemented 
and kinks worked out. In case of OpenJDK 7, for example, support for JSR 
292 was implemented a bit more than a year after the JDK 7 release. [1]

Whether it makes more sense for your porting effort to start with 6, 7 
or 8 ultimately depends on how well the respective release is being 
supported in IcedTea by the alternative VM of your choice. I'm not aware 
of any documentation covering that, so you'll need to ask on the 
distro-pkg-discuss mailing list.
