[aarch64-port-dev ] Stop spurious O_BUFLEN warnings

[Edward Nevill]

Hi,

The following patch stops spurious warning of the form

OpenJDK 64-Bit Server VM warning: increase O_BUFLEN in ostream.hpp -- output truncated

when invoke with -XX:+PrintFlagsFinal

These are generated by the following code in ostream.cpp

  } else if (vsnprintf(buffer, buflen, format, ap) >= 0) {
    result = buffer;
    result_len = strlen(result);
  } else {
    DEBUG_ONLY(warning("increase O_BUFLEN in ostream.hpp -- output truncated");)
    result = buffer;
    result_len = buflen - 1;
    buffer[result_len] = 0;
  }


So, if vsnprintf returns negative it prints this error. This happens because it is passed a bad format string from globals.cpp.

Regards,
Ed.
