#405 IllegalAccessError on simple application

[tomsontom]

i highly doubt that this setting fixes the problems I also sometimes saw when running a simple application, there must be another reason why the export is not respected or do can you give a reason why the above line should fix something?

[ShawnKleese]

Ok... yes... After some investigating i doubt it self :-/ I had some Problems to execute my Code...

I think this Problem is caused by Java bytecode version is 8 and it should be Java 11.

When it is planed to go for Java 11? I have heard that eclipse Ide sets Java 11 in the next release(2020-09) as minimal JRE Version 11 as PreReq.

[tomsontom]

If i would have to guess it could be a threading issue?

[ShawnKleese]

Here is the Stack. It is executed on the JavaFX Application Thread. I think it is good. Or what you're expecting?

Can you reproduce this constantly? To me this happened only from time to time!

[ShawnKleese]

yes, on every Application Start

[tomsontom]

Ok that's good! So we might have a chance to sort out why that happens because as I said to me this happens not all time and so diagnosing that is very hard. Let's discuss the details in the open ticket

[tomsontom]

so I think i fixed the with problem - https://github.com/eclipse-efx/efxclipse-rt/commit/277e3a703c666794f813f73bb228dc30490063cd
