### Environment

* Dubbo version: master branch latest
* Operating System version: all
* Java version: 1.8

### Step to reproduce this issue
1. start StreamUtils UT
2. using `lsof test-class/StreamUtilsTest.txt` to check opened file handle

### Expected Result
after running all the UT, there shouldn't be any opened handles left

### Actual Result
several file handles left

### How to fix
- `overwrite` the `close` method of `InputStream` constructed in `limitedInputStream` and `markSupportedInputStream`
- `close` the InputStream in corresponding UT
@Test
    public void testMarkSupportedInputStream() throws Exception {
        InputStream is = StreamUtilsTest.class.getResourceAsStream("/StreamUtilsTest.txt");
        assertEquals(10, is.available());
        is = new PushbackInputStream(is);
        assertEquals(10, is.available());
