JDK-8276095 - ciReplay: replay failure due to incomplete ciMethodData information
Description
From 8276095 review:

     } else if (strcmp("version", cmd) == 0) {
      _version = parse_int("version");
      if (_version > REPLAY_VERSION) {
        report_error("unrecognized version");

Vladimir:

Would be nice to print both versions numbers in error message.
Also I would like to be able ignore such error and process file anyway. Is report_error allows it?

Dean:

Currently report_error() saves the error string to be printed later, so to have an error message that requires formatting, I guess I would have to allocate the string using malloc or ResourceObj memory.
Right now the only ignore flag is ReplayIgnoreInitErrors. I could introduce something like ReplayIgnoreAllErrors , or maybe turn this error into a warning.
