We need have a separate “issue triage” session to discuss minor proposals in turn. The following minor issues are being actively promoted by members of the community (e.g. by recent updates to the issue).
Add generics to methods currently returning raw types JMS_SPEC-108
Clarify the difference (if any) between
There’s a complete list of all currently-proposed features (too many to do all of them) on the on the JMS planning long list.
