Description
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:

Here's the relevant section of Heap.java:
