So Java 21 produces different floating point values in a few cases. Some of our tests (4) are sensitive to this.
The "right way" to compare floating point numbers is like this: If(Math.abs(A - B) < epsilon) The TDML runner has outstanding bug https://issues.apache.org/jira/browse/DAFFODIL-2402 which is to add the ability to put xsi:type="double" for example on the expected infoset, and this instructructs the (schema unaware) TDML runner to do comparison using some sort of epsilon comparison like the above Does that seem like the right fix for this? The only alternative I can think of is some sort of conditional infoset construction, so that the expected values can vary for different JVMs. On Sat, Sep 23, 2023 at 2:13 PM Mike Beckerle <mbecke...@apache.org> wrote: > > JVM 21 LTS is now out. > > So I decided to try to building Daffodil using it.
