Greetings Rony,

W O W ! ! ! Bravo!!! A most impressive success milestone!

I am thankful,

A few minutes ago the application did not hang, but worked!

Here a few screenshots to see what it is about:














In case anyone feels masochistic ;) there is the log attached together with the 
application (which is quite demanding without further explanations).

---

Basically the following happens:

  * Rexx runs "MainApp.rex",

  * an instance of the Rexx class "RxMainApplication" gets created which implements the abstract 
Java method named "start" from the abstract JavaFX class named 
"javafx.application.Application" (cf.
    e.g. 
<https://docs.oracle.com/javase/8/javafx/api/javafx/application/Application.html>);
 using BSF magic the ooRexx object gets wrapped up in a Java object of type 
javafx.application.Application,
    cf. line # 146 in "MainApp.rex" and the "launch" method from the 
javafx.application.Application gets invoked; the launch method will set up the JavaFX application 
(GUI) thread and will then invoke
    the method "start" which causes the embedded RxMainApplication object to 
get a message by that name,

  * the "start" method gets a window ("primaryStage") such that the start 
method can do whatever is necessary to setup the user interface, eventually creating a Scene which 
gets put on to the
    primaryStage,

      o there are two scenes created from FXML-files which are defined to use ooRexx as the 
script language (e.g. "<?language rexx?>" PI in the fxml files),

      o the FXMLLoader class will create a Rexx engine for each FXML-file and use it to run any 
embedded Rexx code or script files (e.g. <fx:script 
source="put_FXID_objects_into.my.app.rex" />), which
        will save any JavaFX objects that got created in an ooRexx directory 
stored in .environment such that later one can fetch those JavaFX objects 
simply from ooRexx

      o after the FXMLoader did its work the script engines get destroyed

  * when the primaryStage gets shown ("primaryStage~show") any pending updates 
get carried out from Java, e.g., a TableView gets populated which causes callbacks into 
ooRexx (e.g. calls to the
    PropertyValueFactory which maintains the address book people as Rexx 
objects contained in Java porperties and allows for fetching the Rexx attribute 
values)

      o it is at this point (at the very first callback from Java into ooRexx) 
that the hang occurs

  * line # 912 in the attached "20250816_2335_random_success.txt" is the point where 
"primaryStage~show" gets carried out; immediately following are the terminations of the 
two Rexx engines that got
    created for controlling the two FXML files which contain the GUI definitions

      o the hangs occur either at line # 949, or after line # 952 where an 
AttachThread is attempted to be carried out

Then, after a change in the main program (adding even more debug info), the 
program all of a sudden runs, repeatedly!

The statements that are not carried out if hanging are from line # 953 through line # 1254 (where the "start" method invocation gets ended). All other debug output was created when interacting with the GUI and using some features (see screenshots).

So for the moment I won't change anything and need to take a break.

The context is as follows: a rather complex JavaFX application written in ooRexx sets up a GUI user interface using FXML and defines proxy objects for relaying JavaFX callbacks to the ooRexx peers. This is possible because BSF4ooRexx defines a Java RexxProxy class which can embed an ooRexx object, it also allows for using java.lang.Proxy to camouflage it to any Java interface type needed. Whenever a Java callback occurs, this causes a Java method to be invoked with the proxy object and the Java RexxProxy class then will send the embedded ooRexx object an ooRexx message by the name of the Java method and supplies all Java arguments to the Rexx message (and appends a Rexx directory object to contain context information of the particular invocation in case someone wants to know exactly the invocation context).

This infrastructure has been proven and has been working flawlessly for decades.

The above stack trace comes from such a callback from Java to ooRexx.

What is surprising for me is the hang, and I wonder what the reasons for it 
could be.

Any ideas, hints, and help are highly appreciated!
