Knut Anders Hatlen commented on DERBY-4772:
-------------------------------------------

Hi Kristian,

The patch looks like a good improvement (both increasing the length and changing the type to VARCHAR), but is there any particular reason why we should limit the strings to 128 and to the maximum length of a VARCHAR (32672)?

> I suspect the error can be triggered easily in client/server, but for convenience I'll attach the patch for the test where I see the issue.
