On hold until we can work with the WildFly team on a timeline.

@dmlloyd Did you hear anything from WildFly?

[radcortez]

I've spoken with them recently, and they still need some time to move on.

Everything that supports Jakarta 10 needs to retain security manager support, once only Jakarta EE 11 is exclusively supported security manager support is no longer required. EAP 8.2, by default, will be Jakarta EE 10.

The plan is to fork EAP 8.2 from WF 41 in July, after which point WF is freed from supporting EAP 8.x, so EAP 9 and WF 42 should be safe remove SM.

[cescoffier]

@radcortez any more update?

[radcortez]

The idea was to wait until WF 41 to remove SM, which is scheduled for July.

We can always move with this, knowing that we may have to support a version with SM included.

Let's do a major version bump when we make this change.
