Is posible to create new release of StripesFramework for compatibility with Jakarta EE 9.
rename packages javax -> jakarta
I have some project and I need to move from Tomcat 9.x -> Tomcat 10.x

If you are on Stripes 1.6.0, you can build and try this branch that I just released: https://github.com/StripesFramework/stripes/tree/1.6.0-Jakarta

I have not yet pushed this to the Maven repos. But I know this works on both Tomcat 10.x as well as Payara 6. All unit tests pass, all web tests pass.

Fixed in #104.

Release: https://github.com/StripesFramework/stripes/releases/tag/1.6.0-Jakarta-beta
