Knut Anders Hatlen updated DERBY-3616:
--------------------------------------
Attachment: enc.diff
I think the patch works, but I don't think we need to write our own code to
perform encoding/decoding. Instead, we could use the constructor and getBytes()
method that take the encoding parameter, and specify a well-known 8-bit
encoding (for instance ISO-8859-1). See the attached patch for an example (this
patch makes TableFunctionTest pass, but a real patch should probably create
friendly helper methods around new String() and getBytes()). Another benefit
with this approach, is that we waste less space (one byte maps to one char,
whereas derby-3616-01-improvedEncoding.diff maps one byte to two chars).

> When running the test
> org.apache.derbyTesting.functionTests.tests.lang.TableFunctionTest, it fails
> with the output shown below. This test blocks the proper execution of
> suites.All and it was tested under Ubuntu 7.10 (also tested on Windows Vista
> and it doesn't throw an error there).
> There were 2 errors:
> 1)
> noSpecialCollation(org.apache.derbyTesting.functionTests.tests.lang.TableFunctionTest)java.sql.SQLException:
> The exception 'java.lang.ClassNotFoundException: ERROR XBM0U: No class was
> registered for identifier 495.' was thrown while evaluating an expression.
