-----------------------------------------

ij> connect 'jdbc:derby:memory:db;create=true;territory=en_US;collation=TERRITORY_BASED';
ij> create table t(x varchar(20), y varchar(20));
0 rows inserted/updated/deleted
ij> insert into t values ('abc', 'def');
1 row inserted/updated/deleted
ij> select * from t, sysibm.sysdummy1 where x like y escape ibmreqd;
X                   |Y                   |IBM&
----------------------------------------------
ERROR 38000: The exception 'java.lang.ClassCastException: org.apache.derby.iapi.types.SQLChar
cannot be cast to org.apache.derby.iapi.types.CollationElementsInterface' was thrown while
evaluating an expression.
ERROR XJ001: Java exception: 'org.apache.derby.iapi.types.SQLChar cannot be cast to org.apache.derby.iapi.types.CollationElementsInterface:
java.lang.ClassCastException'.

Or, when using sane jars:

ij> select * from t, sysibm.sysdummy1 where x like y escape ibmreqd;
X                   |Y                   |IBM&
----------------------------------------------
ERROR 38000: The exception 'org.apache.derby.shared.common.sanity.AssertFailure: ASSERT FAILED
All three operands must be instances of CollationElementsInterface' was thrown while evaluating
an expression.
ERROR XJ001: Java exception: 'ASSERT FAILED All three operands must be instances of CollationElementsInterface:
org.apache.derby.shared.common.sanity.AssertFailure'.
