    Description

      void DynamicArchiveBuilder::sort_methods(InstanceKlass* ik) const {
        ...
        Thread* THREAD = Thread::current();
        ...
        ik->vtable().initialize_vtable(true, THREAD); assert(!HAS_PENDING_EXCEPTION, "cannot fail");
        ik->itable().initialize_itable(true, THREAD); assert(!HAS_PENDING_EXCEPTION, "cannot fail");
      }

      The code works today because the two calls should never throw exceptions (there are no allocations, no loader constraint check, etc).

      However, if we change TRAPS to be JavaThread*, we will not be able to do this anymore. (See JDK-8252685).
