In theory could go with 1.6. Since that is being phased out, I would recommend 1.7, to prevent the same issue later on. Pretty sure that is where this problem is coming from, but might be something else.
Just modified it locally to >=virtual/jre-1.7 and >=virtual/jdk-1.7 and merged fine. I would likely make that change to all versions in tree.
I was wrong, recompiled on wrong system without use flag set. It fails even with that increased to 1.7, need to look further as to why.
Please attach the complete build log and /tmp/portage/dev-vcs/subversion-1.9.0/temp/class-version-verify.log
Re-assigning to the maintainer for >=subversion-1.8
