Re: [jira] Commented: (HARMONY-6260) [classlib][luni] RI's
PipedInputStream.read(byte[], int, int) using its PipedInputStream.read(),
but harmony does not.
It's a complicate situation. For example, user can override the read(),
which eats the exception thrown there. And this will make read(byte[], int,
int) pass successful. Since PipedInputStream and PipedOutputStream are
related to the multi thread. User maybe need more control to these
operation.

I see. I will recreate the jira.

Yes, create a JIRA and assign it to the component "Non-bug differences
from RI"

I agree it's better to read data once. With the result of the test case, RI
seems to read one byte first to check the situation, and then read batch
data.
By the way, does harmony has a list about non-bug difference?

He can override read(byte[], int, int) either. I'd like think it's a non-bug
difference, and more, Harmony's implementation is better: reading batch data
once is better than reading one by one byte.
