[kepler-dev] Hypothetical Question: Are there any stakeholders who would object to requiring Java 1.6. Why?

[Dan Higgins]

Hi,
    I think the problem with Java 1.6 on the Mac is bit more subtle than 
just OS X 10.5 and an Intel chip. Note that Apple specifies Intel 64 bit 
processors and OS X 10.5 for the 'official' Java 1.6. Well, I have an 
early MacBook Pro and it happens to use an Intel Core Duo processor. 
Apparently this is NOT a 64 bit chip. Later Intel Macs apparently have 
Intel Core 2 Duo processors which I think qualify as 64 bit. In any 
case, I cannot get Java 1.6 running on my MacBook Pro. So requiring 1.6 
for Kepler would create problems for all PPC Macs and some Intel Macs.
