    John,

    Could you tell me what kind of OS is running on your
    4-way SMP machine ? And on you laptop ?

    Thanks,
    Bart

    SMP: Red Hat Enterprise Linux (not sure of version); JVM is HotSpot
    1.5.0_10-b03

    Laptop: Edgy Eft version of Ubuntu Linux; JVM is HotSpot 1.5.0_04-b05

    My guess is that it's likely to be a timing-sensitive thing. The
    property trigger stuff looked suspicious, but I tried disabling that out
    and it still happens. I also tried disabling
    testFormatStringExpressionCubeNoCache (since it runs just before and has
    cache disabled on a base cube underlying a virtual cube) but the failure
    still occurred.

    Something interesting: I noticed that HotSpot was automatically
    selecting Server mode on the SMP machine (whereas on my laptop it
    autoselects Client mode). I changed build.xml to force usage of Client
    mode, and then "ant test" ran through with no failures.

    Haven't tried forcing Server mode on laptop yet; if it's timing-related,
    it may just be that it takes the combination of a very fast machine plus
    Server mode to hit it.

    Also, Bart, if you want to send me code modifications to enable tracing
    targeted at debugging the problem, please do, and I'll run it through on
    the SMP machine and send you the output.
