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.
