The discussion about SLE seems to have taken over.
This was originally about zLinux.

If it actually makes sense for zLinux for JDK 11 then I have no 
objections to
the proposed toolchain specific patch ...

If it does not make sense for 11 then I think you should look only at 8u 
and prepare
a patch directly against that.

Its not "critical" for 10 which is in RDP2 already and 9 is going EOSL 
in less than 3 months  ...
