    Dear Community,
    
    may I please request reviews for this tiny change.
    
    The vtable stub generator issues a VM call which is highly dynamic in size. The hardwired size estimate has proven to be a bit too small at times. We ran into the related assert failure when using -XX:+DebugVtables. The change simply increases the estimate.

    Testing: SAP-internal nightly tests (OK), jdk/submit (pending).
    
    Thanks,
    Lutz
