A few days ago, Apple revealed their plan to give up providing Java Runtime versions for Mac OS X. There was quite some speculation if this means Apple plans to diss Java similarly to Flash.
But obviuosly, they really just said: we’re not investing anything any more, but we welcome Oracle to do that for our platform.
Which is what will happen: Apple just announced that they will support Java 6 on Snow Leopard and Lion, and Java 7 will be provided by Oracle. This is true for many platforms, so the Mac will be like all the others.
So we’ll have Java and Eclipse on our Macs for quite some years to come.
