[aix] loadquery failed error reported

There is a scenario where in a Java program after loading some shared
libraries (using System.loadLibrary) and then calling
javax.imageio.ImageIO.read(new File(..)) the java program displays the
following error message:

loadquery failed (12 Not enough space)

This happens when running on AIX with Java 11 using this sample code:

import java.io.File;
import java.util.Map;
import javax.imageio.ImageIO;
public class Reproduce {
    public static void main(String[] args) {
        try {
            System.loadLibrary("mylib");

            String filePath = "...";
            BufferedImage img = ImageIO.read(new File(filePath));

        }
        catch (Throwable e) {
            System.out.println("Exception : " + e);
            e.printStackTrace();
        }
    }
}

It seems that this is displayed from
src/java.desktop/aix/native/libawt/porting_aix.c

static unsigned char dladdr_buffer[0x4000];

static void fill_dll_info(void) {
  int rc = loadquery(L_GETINFO,dladdr_buffer, sizeof(dladdr_buffer));
  if (rc == -1) {
    fprintf(stderr, "loadquery failed (%d %s)", errno, strerror(errno));
    fflush(stderr);
  }
}

and is due to the dladdr_info buffer being too small to contain all the
data returned from the loadquery function.

The same buffer size is also used in
src/java.base/aix/native/libjli/java_md_aix.c
