Thiago Henrique Hupner commented on TOMEE-2838:
-----------------------------------------------
For Jackson Databind 2.10:
The constant:
[https://github.com/FasterXML/jackson-databind/blob/2.10/src/main/java/com/fasterxml/jackson/databind/ext/OptionalHandlerFactory.java#L31]
[https://github.com/FasterXML/jackson-databind/blob/2.10/src/main/java/com/fasterxml/jackson/databind/ext/OptionalHandlerFactory.java#L104]
[https://github.com/FasterXML/jackson-databind/blob/2.10/src/main/java/com/fasterxml/jackson/databind/ext/OptionalHandlerFactory.java#L137]
> Jackson uses "javax.xml."

> Key: TOMEE-2838
> URL: https://issues.apache.org/jira/browse/TOMEE-2838
> Project: TomEE
> Issue Type: Sub-task
> Reporter: David Blevins
> Priority: Major
>
> In Jakarta EE 9 all the APIs have been repackaged from javax to jakarta. For
> example `javax.servlet.http.HttpServlet` becomes
> `jakarta.servlet.http.HttpServlet`
>
> We're using tooling to perform bytecode transformation on all the jars and
> classes in TomEE 8 so that we can create a distribution of TomEE that can be
> made both Jakarta EE 8 and Jakarta EE 9 compliant. When the references are
> classes, it's very easy. When the references are strings, it's harder as you
> have to look at the code and see what it is doing with the string and if its
> logic will still work or if it needs to be adjusted.
>
> In various versions of Jackson there seems to be a part of the code using the
> string "javax.xml." We need to investigate to figure out what it might be
> trying to learn or do with that string.
> *Uses spotted in bytecode*

> The most sane way to investigate would probably be to download the source

> make sure to get the source code for the version of Jackson that is in TomEE
> 8.0.3-SNAPSHOT.

> If it is a mix of the two, then it's still broken and we'll have to try and
