Recently, we see an increased number of build failures in java and libreoffice

it *seems* (felt, a couple log files checked) to be related to the Kernel 4.3.0
upgrade in Tumbleweed

For example:
https://build.opensuse.org/package/live_build_log/openSUSE:Factory:Staging:G:DVD/java-1_7_0-openjdk/standard/x86_64

The build log contains:
