Knut Anders Hatlen updated DERBY-3616:
--------------------------------------
Attachment: no-encoding.diff
I guess the best solution is to skip the encoding/decoding steps entirely. See
the attached patch (no-encoding.diff). That patch stores the TypeDescriptor in
a saved object in the Activation. Then all the encoding/decoding logic in
FormatIdUtil could be removed, as could FromVTI.freezeReturnType() and
VTIResultSet.thawReturnType().
I have only run the TableFunctionTest, which passed in an environment where it
failed before Rick's fix was checked in. I'll run the entire test suite and
commit the patch if there are no objections to this approach.

> When running the test
> org.apache.derbyTesting.functionTests.tests.lang.TableFunctionTest, it fails

> and it doesn't throw an error there).
> There were 2 errors:
