Subject [jira] Commented: (DERBY-2604) Implement Clob support for locators

Knut Anders Hatlen commented on DERBY-2604:
-------------------------------------------

Hi Narayanan, I haven't looked at the entire patch, only ClobLocatorInputStream.java, but
I have a couple of comments:

1) readBytes() doesn't look correct to me. It takes a len parameter, which is length in bytes,
and passes it on to clobGetSubString(), which expects length in characters. This means that
the byte array returned by readBytes() might contain more bytes than len. I cannot see that
read() or read(byte[],int,int) are prepared for this.

2) The boundary checking in read(byte[],int,int) might suffer from int overflow. (off+len
> b.length) should be replaced with (len > b.length - off).

3) clob and connection could be final, I think.
