AFAICT this is a new/similar instance of #814411, i.e. just a path issue for libjvm.so. For instance, rjb works for me again if I do:
mkdir -p /usr/lib/jvm/jre/lib/amd64/server/
ln -s /usr/lib/jvm/java-9-openjdk-amd64/lib/server/libjvm.so \
/usr/lib/jvm/jre/lib/amd64/server/libjvm.so
So I guess 0005-Always-JVM_TYPE-to-server.patch should be updated some how.
