blacksea3 opened a new issue, #4778:
URL: https://github.com/apache/servicecomb-java-chassis/issues/4778
### Steps to Reproduce
cse 2.8.20版本
org.apache.servicecomb.foundation.vertx.stream.BufferInputStream流 int
read()方法读取单字节，如果读取到流末尾会抛异常IndexOutOfBoundsException
示例代码1: 单独构造失败用例
public class CseBufferInputStream {
public static void main(String[] args) throws IOException {
byte[] byteArray = new byte[10];
BufferedReader br = null;
try {
// 由于StsCseServerFilter要在此Filter之前执行，所以，需要重置码流，将ridx置0
InputStream inputStream = getRealInputStream(byteArray);
if (inputStream == null) {
return;
}
inputStream.reset();
while (inputStream.read() >= 0) {
;
}
} finally {
IOUtils.closeQuietly(br);
}
}
public static InputStream getRealInputStream(byte[] byteArray) {
// 创建 UnpooledSlicedByteBuf
ByteBuf slicedByteBuf = Unpooled.wrappedBuffer(byteArray);
// 创建 BufferInputStream，这个stream类型，以及里面的Buffer和真实的走CSE请求的一致
InputStream inputStream = new BufferInputStream(slicedByteBuf);
return inputStream;
}
}
运行结果
org.apache.servicecomb.foundation.vertx.stream.BufferInputStream流 int
read()方法读取单字节，如果读取到流末尾会抛异常IndexOutOfBoundsException
示例代码2: 实际应用
/**
* gzip解压
* @param byteArray gzip压缩数据
*
* @throws IOException IOException
*/
public static void gzipRead(byte[] byteArray) throws IOException {
BufferedReader br = null;
try {
// 由于StsCseServerFilter要在此Filter之前执行，所以，需要重置码流，将ridx置0
InputStream inputStream = getRealInputStream(byteArray);
if (inputStream == null) {
return;
}
inputStream.reset();
br = new BufferedReader(new InputStreamReader(new
GZIPInputStream(inputStream), "UTF-8"));
char[] readBuff = new char[2048];
while ((br.read(readBuff)) > 0) {
}
} finally {
IOUtils.closeQuietly(br);
}
}
public static InputStream getRealInputStream(byte[] byteArray) {
// 创建 UnpooledSlicedByteBuf
ByteBuf slicedByteBuf = Unpooled.wrappedBuffer(byteArray);
// 创建 BufferInputStream，这个stream类型，以及里面的Buffer和真实的走CSE请求的一致
InputStream inputStream = new BufferInputStream(slicedByteBuf);
return inputStream;
}
调用gzipRead方法，传一个正确的gzip压缩二进制流进去， 在 java 1.8.0_432 会报错，其原因同 示例1一致，
int read()方法读取单字节，如果读取到流末尾会抛异常IndexOutOfBoundsException
详细调用链见图 java 1.8.0_432 见红色流程。
### Expected Behavior
org.apache.servicecomb.foundation.vertx.stream.BufferInputStream流 实现
java.io.InputStream
没字节的时候 应该返回-1，接口定义如下
