Hi there

using foxtrot with java 1.8 i obtained the folling message :

WARNING: An illegal reflective access operation has occurred
WARNING: Illegal reflective access by foxtrot.pumps.ConditionalEventPump$1 (file:/N:/AppName/lib/foxtrot-core-4.0.jar) to method java.awt.EventDispatchThread.pumpEvents(java.awt.Conditional)
WARNING: Please consider reporting this to the maintainers of foxtrot.pumps.ConditionalEventPump$1
WARNING: Use --illegal-access=warn to enable warnings of further illegal reflective access operations
WARNING: All illegal access operations will be denied in a future release

using the suggested --illegal-access=warn i obtained :

WARNING: Illegal reflective access by foxtrot.pumps.ConditionalEventPump$1 (file:/project/lib/foxtrot-core-4.0.jar) to method java.awt.EventDispatchThread.pumpEvents(java.awt.Conditional)
WARNING: Illegal reflective access by foxtrot.pumps.SunJDK141ConditionalEventPump$1 (file:/N:/AppName/lib/foxtrot-core-4.0.jar) to method java.awt.SequencedEvent.getFirst()

I usually use this fragment to invike foxtrot :

Worker.post(CLASS_TO_INVOKE);

and CLASS_TO_INVOKE extends Job

Any ideas about?

Best regards

Paolo,

yes, Foxtrot does deep reflection on AWT classes.

However, Foxtrot is now a bit out of date, it served a purpose back in the days of JDK 1.3.

With JDK 1.7, a standard API for pumping AWT events has been added to the JDK, so applications should rely on that instead, see https://docs.oracle.com/javase/7/docs/api/java/awt/EventQueue.html#createSecondaryLoop().

Ciao!

[Paolo Ucchino]

The strength of foxtrot compared to swingutilities is undoubtedly the
possibility of using its "Synchronous Solution".

Using the API you mentioned, it is possible to replicate the feasibility
using the secondaryloop (
https://docs.oracle.com/javase/7/docs/api/java/awt/SecondaryLoop.html) i
see... Is it correct?

Using a barbarian method and not wanting to go into detail it would be
equivalent to invoke SwingUtilities.invokelater and then open a modal
dialog.

Foxtrot could have an implementation based on SecondaryLoop, but this was not done.

Rather than using SwingUtilities.invokelater(), you want to do this (did not try, just to give you an idea):

Executor executor = ...;

EventQueue queue = Toolkit.getDefaultToolkit().getSystemEventQueue();
SecondaryLoop loop = queue.createSecondaryLoop();
executor.execute(() -> {
    doWork();
    loop.exit();
});
loop.enter();

Ciao!

[Paolo Ucchino]

confess I'm sorry to leave foxtrot but what to say ... it's time.

Thanks for the support Simone.

Ciao!

@Paolo

well, perhaps you don't need to leave it. I may have some time to look at the project and implement the pump using SecondaryLoop.

Cheers

[Raymond Martin]

Hi, so is there any chance of this change over to SecondaryLoop in the foreseeable future? I will have to gut an appalication I made with Foxtrot otherwise to get around the synchronization issues it had before using the lib. Thanks.
