Hey @joaquinfelici, can you share some information/documentation about the changes in those PRs? It's hard to understand why they are necessary.

[joaquinfelici]

Hey @mboskamp , discussed with Tassilo who took care of most of this fix. Spring 5 is EOL, so we're changing the default spring version to 6 for the engine. Spring 5 is still supported but must be explicitly overridden. Websphere Liberty and other impacted distros continue using spring 5, hence the exclusions. The JNDI changes are due to a change in Spring, now the testing library for JNDI was removed, and they propose to add simple-jndi (more info here).

I left a few comments/questions in the PRs.
