Agenda: 1. M2 build process doesn't put correct MANIFEST.MF in jar file https://issues.apache.org/jira/browse/JDO-634Looks like it's easy to generate OSGi information in the manifest by using the felix plugin. Anything besides the OSGi missing?
2. List.get(int) support in JDOQL is missing https://issues.apache.org/jira/browse/JDO-633The change to the specification is one line. Implementation in the RI sounds straightforward. I'd say it's too late for JDO 2.3 but it can be implemented and tested with DataNucleus and considered for a future update.
3. Other issueshttp://issues.apache.org/jira/browse/JDO-623 How to create a query that is "guaranteed" to run slow enough that another thread can cancel it? Perhaps something like this would work: "SELECT AVG(t0.c1 + t1.c1 + t2.c1) FROM t0, t1, t2" where t0, t1, and t2 are simply tables with columns c0 INT, c1 INT. With a relatively small number of rows (100) you would have the query do an outer join of 100 * 100 * 100 rows (1,000,000 rows). If the optimizer can calculate the average by itself, you might add "WHERE t0.c1 > 1 AND t0.c1 < 1000" to avoid the optimization.
