Java：使用axis做RPC调用时，如果返回的字符串中含有\r\n，为什么axis会将\r\n替换成\n？

在org.apache.xerces.impl.XMLEntityScanner的方法public int scanContent(XMLString content)中舍弃了\r，
原代码：

int offset = fCurrentEntity.position;
int c = fCurrentEntity.ch[offset];
int newlines = 0;
boolean external = fCurrentEntity.isExternal();
if (c == '\n' || (c == '\r' && external)) {if (DEBUG_BUFFER) {System.out.print("[newline, "+offset+", "+fCurrentEntity.position+": ");XMLEntityManager.print(fCurrentEntity);System.out.println();}do {c = fCurrentEntity.ch[fCurrentEntity.position++];if (c == '\r' && external) {newlines++;fCurrentEntity.lineNumber++;fCurrentEntity.columnNumber = 1;if (fCurrentEntity.position == fCurrentEntity.count) {offset = 0;fCurrentEntity.baseCharOffset += (fCurrentEntity.position - fCurrentEntity.startPosition);fCurrentEntity.position = newlines;fCurrentEntity.startPosition = newlines;if (load(newlines, false)) {break;}}if (fCurrentEntity.ch[fCurrentEntity.position] == '\n') {fCurrentEntity.position++;offset++;}/*** NEWLINE NORMALIZATION ***/else {newlines++;}}else if (c == '\n') {newlines++;fCurrentEntity.lineNumber++;fCurrentEntity.columnNumber = 1;if (fCurrentEntity.position == fCurrentEntity.count) {offset = 0;fCurrentEntity.baseCharOffset += (fCurrentEntity.position - fCurrentEntity.startPosition);fCurrentEntity.position = newlines;fCurrentEntity.startPosition = newlines;if (load(newlines, false)) {break;}}}else {fCurrentEntity.position--;break;}} while (fCurrentEntity.position < fCurrentEntity.count - 1);for (int i = offset; i < fCurrentEntity.position; i++) {fCurrentEntity.ch[i] = '\n';}

修改方式是将一些行注释掉，见有//的行：

int offset = fCurrentEntity.position;
int c = fCurrentEntity.ch[offset];
int newlines = 0;
boolean external = fCurrentEntity.isExternal();
if (c == '\n' || (c == '\r' && external)) {if (DEBUG_BUFFER) {System.out.print("[newline, "+offset+", "+fCurrentEntity.position+": ");XMLEntityManager.print(fCurrentEntity);System.out.println();}do {c = fCurrentEntity.ch[fCurrentEntity.position++];if (c == '\r' && external) {newlines++;fCurrentEntity.lineNumber++;fCurrentEntity.columnNumber = 1;if (fCurrentEntity.position == fCurrentEntity.count) {offset = 0;fCurrentEntity.baseCharOffset += (fCurrentEntity.position - fCurrentEntity.startPosition);fCurrentEntity.position = newlines;fCurrentEntity.startPosition = newlines;if (load(newlines, false)) {break;}}if (fCurrentEntity.ch[fCurrentEntity.position] == '\n') {fCurrentEntity.position++;
//                offset++;}/*** NEWLINE NORMALIZATION ***/else {newlines++;}}else if (c == '\n') {newlines++;fCurrentEntity.lineNumber++;fCurrentEntity.columnNumber = 1;if (fCurrentEntity.position == fCurrentEntity.count) {offset = 0;fCurrentEntity.baseCharOffset += (fCurrentEntity.position - fCurrentEntity.startPosition);fCurrentEntity.position = newlines;fCurrentEntity.startPosition = newlines;if (load(newlines, false)) {break;}}}else {fCurrentEntity.position--;break;}} while (fCurrentEntity.position < fCurrentEntity.count - 1);
//    for (int i = offset; i < fCurrentEntity.position; i++) {
//        fCurrentEntity.ch[i] = '\n';
//    }
