项目上传一个大约2G的shipe文件 需要转换坐标，平时上传小的文件挺正常的， 这次上传了一个大的文件就报BufferUnderflowException异常了，有大神知道怎么回事么， 代码如下：
public static JSONObject generateW84Shapefile(
SimpleFeatureSource featureSource, String shapeFileName, File inputFolder, File outputFolder,
boolean keepFileName, int fileCoordinateType) throws JSONException {
JSONObject jo = new JSONObject();
try {
if (!outputFolder.exists()) {
outputFolder.mkdirs();
}
SimpleFeatureType schema = featureSource.getSchema();
CoordinateReferenceSystem dataCRS = schema.getCoordinateReferenceSystem();
if (dataCRS == null) { // can't find projection
log.error("Error: Can't find the projection of the uploaded shapefile.");
jo.put("Error", "Can't find the projection of the uploaded shapefile.");
} else {
Integer epsgCode = -1;
try {
epsgCode = CRS.lookupEpsgCode(dataCRS, true);
log.info("EPSG code of the source feature: " + epsgCode);
} catch (Exception ee) {
log.error("Error in finding the EPSG code of the source feature", ee);
}
int count = 0;
if (epsgCode == null || epsgCode != 4326 || fileCoordinateType != 1) {
CoordinateReferenceSystem wgs84CRS = CRS.decode("EPSG:4326");
File newShapeFile = new File(outputFolder,
shapeFileName + ((keepFileName || fileCoordinateType == 1) ? ".shp" : "_gcj02.shp"));
DataStoreFactorySpi factory = new ShapefileDataStoreFactory();
Map<String, Serializable> create = new HashMap<String, Serializable>();
create.put("url", newShapeFile.toURI().toURL());
create.put("create spatial index", Boolean.TRUE);
DataStore dataStore = factory.createNewDataStore(create);
SimpleFeatureType featureType = SimpleFeatureTypeBuilder.retype(schema, wgs84CRS);
dataStore.createSchema(featureType);
// Get the name of the new Shapefile, which will be used to
// open the FeatureWriter
String createdName = newShapeFile.getName().substring(0, newShapeFile.getName().lastIndexOf('.'));
Transaction transaction = new DefaultTransaction("Reproject");
FeatureWriter<SimpleFeatureType, SimpleFeature> writer = dataStore
.getFeatureWriterAppend(createdName, transaction);
SimpleFeatureCollection featureCollection = featureSource.getFeatures();
SimpleFeatureIterator iterator = featureCollection.features();
boolean projected = true;
MathTransform transform = null;
boolean lenient = true; // allow for some error due to
// different datums
transform = CRS.findMathTransform(dataCRS,wgs84CRS, lenient);
try {
while (iterator.hasNext()) { **//这一行报的错**
// copy the contents of each feature and transform
// the geometry
SimpleFeature feature = iterator.next();
SimpleFeature copy = writer.next();
copy.setAttributes(feature.getAttributes());
Geometry geometry = (Geometry) feature.getDefaultGeometry();

} else {

}
if(fileCoordinateType == 2) {//bd09
geometry2 = GCJConverter.bd09toGCJ(geometry2);
}else if(fileCoordinateType == 3) {
geometry2 = GCJConverter.toGCJ(geometry2);
}
copy.setDefaultGeometry(geometry2);
writer.write();
count++;
}
writer.close();
transaction.commit();
} catch (Exception e) {
e.printStackTrace();
projected = false;
log.error("Error: Can't reproject the uploaded shapefile.", e);
log.info("count===>"+count);
transaction.rollback();
} finally {
transaction.close();

iterator.close();
}
if (!projected) {

} else {

}
}
}
} catch (Exception e) {
