> While working with Eranda on DERBY-4187, I stumbled across an apparent ALTER TABLE bug.
> Here's a script which reproduces the problem for me:
> autocommit off;
> create table t0(c1 int not null constraint p1 primary key);
> alter table t0 add column c1 int;
> alter table t0 add column c2 int not null default 0 primary key;
> alter table t0 add column c2 int not null default 0;
> The "autocommit off" is crucial; otherwise the problem does not reproduce.
> Here's the detailed assertion failure:
