Subject [jira] Commented: (HARMONY-6576) [classlib][luni] PipedOutputStream.write throws PipeNotConnected Exception
Date Fri, 16 Jul 2010 06:55:55 GMT

    [ https://issues.apache.org/jira/browse/HARMONY-6576?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12889026#action_12889026
] 

Regis Xu commented on HARMONY-6576:
-----------------------------------

            assertEquals(
                    "IndexOutOfBoundsException rather than a subclass expected",
                    IndexOutOfBoundsException.class, t.getClass());

why exception thrown can't be a subclass of IndexOutOfBoundsException ?


+		try {
+            pis = new PipedInputStream();
+            pos = new PipedOutputStream(pis);
+            pos.close();
+            pos.write(new byte[0], 0, 0);
+            // expected
+        } catch (IOException e) {
+            fail("should not throw IOException");
+        }

here the try cache is not necessary.

> The below testcase throws PipeNotConnected exception when trying to write
> a zero byte array just after closing the stream.
> The exception should not be thrown as there is no byte to write.
