Igniters!
I think it's time to change coding guidelines in part of JavaDoc comments
[1]:
>> Every method, field or initializer public, private or protected in
top-level,
>> inner or anonymous type should have at least minimal Javadoc comments
including
>> description and description of parameters using @param, @return and
@throws Javadoc tags,
>> where applicable.
Let's look at JavaDoc comments in the IgniteKernal class:
Why?
/** */ - 15 matches.
What can you get new from these comments?
/** Periodic starvation check interval. */
private static final long PERIODIC_STARVATION_CHECK_FREQ = 1000 * 30;
/** Long jvm pause detector. */
private LongJVMPauseDetector longJVMPauseDetector;
/** Scheduler. */
private IgniteScheduler scheduler;
/** Stop guard. */
private final AtomicBoolean stopGuard = new AtomicBoolean();
/**
* @param cfg Configuration to use.
* @param utilityCachePool Utility cache pool.
* @param execSvc Executor service.
* @param sysExecSvc System executor service.
* @param stripedExecSvc Striped executor.
* @param p2pExecSvc P2P executor service.

public void start(
final IgniteConfiguration cfg,

These comments look ugly and useless, and that is the main class of core.
Why do they need us?
Let us change the coding guidelines in part of JavaDoc comments:
Every method public API should have at least minimal Javadoc comments,
including description and description of parameters using @param, @return,
and @throws Javadoc tags,
where applicable.
For internal API, JavaDoc comments should be optional. It's up to a
contributor or reviewer.
