I thought it failed with earlier openjdk than that because of jgdi being removed, but I think it needs to use aimk -no-java ... I don't know what JDK versions it needs to check for, but it's probably not worth any effort to get that right. I'm not sure whether you can still build jdrmaa, at least. I look at it immediately, but can probably can in a bit as I need to resurrect rpm builds anyway.
