    Could be related to the fix for JDK-8028497: SIGSEGV at ClassLoaderData::oops_do(OopClosure*, KlassClosure*, bool), which moved where the size is set for java/lang/Class-objects (thanks mgerdin!).
    Similar failure can also be seen in JDK-7005510: DynamicProbes01 fails with "assert(DTraceAllocProbes) failed: wrong call", although I don't know if it's the same underlying issue.
