I'm not sure what you mean. SLE12-SP3 ships gcc-4.8.x while SLE-15 will
ship gcc-7, see:

Is that what you mean when you say the gcc version is changing?

I don't know what the minimum version is at the moment, to be honest. I haven't
tried building OpenJDK-10 or OpenJDK-11 on SLE-12:SP3 yet. I could do that
if that's important.

It most likely doesn't break anything. But it leaves workaround in the code
base which we could potentially forget to clean out later when it is no
longer needed.

My opinion is that the codebase for OpenJDK-11 should be kept clean because
we are working on getting rid of unnecessary cruft. But this decision isn't
up to me, of course. I'm just arguing that I consider the chances that someone
will try OpenJDK-11 on SLE-12:SP3 or even SLE-11:SP4 very low.
