I have tested the integrity of the jar on windows -- which says fine. Then host file system is mounted in ubuntu guest (amd64 bit, 10.04 with latest updates). Now do a copy and paste of the jar from windows file system to ubuntu filesystem (within the guest). Now check the integrity of the jar on the ubuntu - integrity test fails. defect closed guest additions VirtualBox 3.2.8 fixed Linux Windows
