This failure occurs as Yoko depends on private
java.lang.Class.computeSerialVersionUID method which is of course not present
in Harmony.
The org.apache.yoko.rmi.impl.ValueDescriptor.getSerialVersionUID code looks
very strange as some sort of hacky performance optimization. I've made simple
patch which fixes the problem by removing all the suspicious code.
