[OH3] Rescheduling timer failed

[MarcinJakubczyk]

Reschedule timer ends with warning log and no action:
[WARN ] [el.script.internal.actions.TimerImpl] - Rescheduling failed as execution has already started!

Documentation says this should be possible:
Reschedules a timer to a new starting time. This can also be called after a timer has terminated, which will result in another execution of the same code.
source: https://openhab.org/javadoc/latest/org/openhab/core/model/script/actions/timer#reschedule(java.time.ZonedDateTime)

Example rule:

var Timer testTimer

rule "Reschedule test"
when
    Item TestSwitch changed
then
    logInfo("RescheduleTest", "TestSwitch changed")

    if (testTimer !== null)
    {
        logInfo("RescheduleTest", "Timer state: " + testTimer.hasTerminated + testTimer.isRunning + testTimer.isActive)

        testTimer.reschedule(now.plusSeconds(10))
    }
    else
        testTimer = createTimer(now.plusSeconds(10), [|
            logInfo("RescheduleTest", "Test timer fired")])
end

Test switch:

Switch  TestSwitch
