The error appears to be intentional:

        jint field_offset = field->u.boffset;
        if (field_offset > 0xffff)
          throw new java::lang::VirtualMachineError;

However, I don't know what purpose this could serve.
Perhaps it is a mistake on the part of the original author,
thinking that this somehow reflects the internal limit
of 65535 fields per .class file.
