A DESCRIPTION OF THE PROBLEM :
create new BufferedInputStream(new FileInputStream(file)),  In some scenarios,  available() will always return Integer.MAX_VALUE,  show the code as folows:
public synchronized int available() throws IOException {
        int n = count - pos;
        int avail = getInIfOpen().available();
        return n > (Integer.MAX_VALUE - avail)
                    ? Integer.MAX_VALUE
                    : n + avail;
    }

I believe that getInIfOpen().available return negative number, so Integer.MAX_VALUE - avail  return negative number because of numerical overflow.

Consider the example code as folows:
	public static void main(String[] args) {
		String filePath = "test"; // file length = 10;
		File file = new File(filePath);
		InputStream inputStream = null;
		try {
			inputStream = new BufferedInputStream(new FileInputStream(file));

			byte[] buffer1 = new byte[5];
			inputStream.read(buffer1, 0, buffer1.length);

			byte[] buffer2 = new byte[5];
			inputStream.read(buffer2, 0, buffer2.length);

			inputStream.skip(1);

			inputStream.available(); // return Integer.MAX_VALUE
		} catch (Exception e) {
			System.out.println(e);
		} finally {
			if (null != inputStream) {
				try {
					inputStream.close();
				} catch (Exception e2) {
					System.out.println(e2);
				}
			}
		}
	}
