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

    Attachment: patch2_setOffset_fullcoll.out

Mamta, thanks for all your work on this. You are right, the NPE's are gone!  I still see an
exception:

1) testWildcardAsEscape(org.apache.derbyTesting.functionTests.tests.lang.DynamicLikeOptimizationTest)java.sql.SQLException:
Escape character must be followed by escape character, '_', or '%'. It cannot be followed
by any other character or be at the end of the pattern.

I have not reviewed the code yet. I will do that after you post the new patch.

> With TERRITORY_BASED collation '_' does not match  the character \uFA2D.  It is the same
for english or norwegian. FOR collation UCS_BASIC it matches fine.  Could you tell me if this
is a bug?
> Here is a program to reproduce.

>    {
>    System.out.println("\n Territory no_NO");
>    Class.forName("org.apache.derby.jdbc.EmbeddedDriver");

>    conn = DriverManager.getConnection("jdbc:derby:endb;create=true;territory=en_US;collation=TERRITORY_BASED");
>    testLikeWithHighestValidCharacter(conn);
>    conn.close();
