EXCEPTION_ACCESS_VIOLATION, when using GDAL Java API

[jimmyzhao]

I use GDAL Java API to write raster data to Oracle Spatial GeoRaster Object, and encouter a strange problem:

" # # A fatal error has been detected by the Java Runtime Environment:

"

This is my Java codes:

import java.nio.ByteBuffer;

import org.gdal.gdal.Band;
import org.gdal.gdal.Dataset;
import org.gdal.gdal.Driver;
import org.gdal.gdal.gdal;
import org.gdal.gdalconst.gdalconstConstants;


public class GDALTest3 {

	public static void main(String[] args) {

		Dataset dataset1;
		Dataset dataset2;
		
		Band band1;
		Band band2;
		
		Driver driver;
		
		gdal.AllRegister();
		
		driver = gdal.GetDriverByName("georaster");
		
		dataset1 = gdal.Open("geor:georaster/georaster@orcl,rdt_01,1");
		band1 = dataset1.GetRasterBand(1);
		
		int xSize = dataset1.getRasterXSize();
		int ySize = dataset1.getRasterYSize();
		int bands = dataset1.getRasterCount();
		
		String options[] = new String[]{"INSERT=VALUES(103, 'new.tif', SDO_GEOR.INIT('rdt_01',3))", "BLOCKXSIZE=512", "BLOCKYSIZE=512"};
		dataset2 = driver.Create("georaster:georaster/georaster,,georaster_table,georaster",
				xSize, ySize, bands, band1.getDataType(), options);
		
		dataset2.SetGeoTransform(dataset1.GetGeoTransform());
		dataset2.SetProjection(dataset1.GetProjection());
		
		band2 = dataset2.GetRasterBand(1);
		
		ByteBuffer buffer = ByteBuffer.allocateDirect(xSize);
		
		for( int i =0; i < ySize; i++ ) {
			
			buffer = band1.ReadRaster_Direct(0,i,xSize,1);
			
			band2.WriteRaster_Direct(0,i,xSize,1,buffer);
		}
		
		dataset2.FlushCache();
		
		System.out.println("generate a new georaster : " + dataset2.GetDescription());
		
		dataset1.delete();
		dataset2.delete();		
	}

}

When executing the sentence "Dataset2.FlushCache();", the above problem rises.

By the way, I can use gdal_translate to load GTiff file to Oracle Georaster database successfully, and I can also export Oracle Spatial GeoRaster data to GTiff file with GDAL Java API. But why can't I use GDAL Java API to load GTiff file to Oracle GeoRaster database?

The version of GDAL is 1.7.1, and it is compiled with Visual Studio 2008. The GTiff image is 183MB with 3 bands. The log of exact error is attached.
