I believe DERBY-5953 is a duplicate.

> You can't use CREATE TABLE AS SELECT from a table with a BOOLEAN column. This limitation
was put in when CREATE TABLE AS SELECT was added. At that time you could not create user tables
with BOOLEAN columns and we did not want people to be able to subvert that restriction by
using CREATE TABLE AS SELECT from a system table with BOOLEAN columns. The following script
shows this problem:
> connect 'jdbc:derby:memory:db;create=true';
> create table t1( a int );
> create table t2( a boolean );
> create table t3 as select * from t1 with no data;
> create table t4 as select * from t2 with no data;
