----------------------------
I saw two failures when running suites.All with weme6.1 last night, both in
TableTestFunction with similar diffs. Ex:
noSpecialCollation(o.a.dTesting.functionTests.tests.lang.TableFunctionTest)java.sql.SQLException:
An attempt was made to get a data value of type 'java.lang.Object' from a data
value of type 'DECIMAL'.

The other failure was the "specialCollation()" fixture.
I'm guessing you're not running tests with weme6.1, but any chance you might be
able identify the cause? Or should I file a separate issue?
> TABLE FUNCTION returning CHAR values does not return a correct value if the
> Java ResultSet class returns a value less than the length of the defined CHAR.

> Defining a column in the returned type as CHAR(10) requires that the returned
> value be of length 10 characters.
> Defining a table function with a return type of:
> returns TABLE column0 char( 10 ), column1 char( 10 ))
> seems to just return whatever the Java ResultSet implementation handed it.
> My guess this is true for all variable length types, no casting of the value
> occurs when it is returned to the SQL domain.
> Java single value functions and procedure out parameters do perform any
> required casting to ensure the value is of the declared type.
