Bryan Pendleton commented on DERBY-1471:
----------------------------------------
May I suggest an alternate wording for the new error message? Instead of
<text>Length of LOB was retrieved though it was unknown
yet.</text>
I suggest
<text>The length of this BLOB/CLOB is not available yet. When a BLOB or
CLOB is accessed as a stream, the length is not available until the entire
stream has been processed.</text>
Also, one other question on the patch, regarding the change to
o.a.d.client.am.Lob:
when will it be the case that the agent_.connection_ instance is *not* an
instance
of NetConnection? Don't we always have a NetConnection instance here?
The rest of the patch looks good to me.
