Hello @Erel ;

I have sometimes read error when Run(debug mode)
I see the error many times in a row. when connection java and app at start.

it works normally sametimes when it Rebulid or save project or closing desinger ide.
then everything works normally.
For now, it has no effect on my project, it can only be annoying.
you said before " the virus program blocked connection with java or app"
But now; sometime a lot of time repat it.
I use Kaspersky, some times coled it. But its not effect. B4J close-re_open... all wys tried.
its broken.

is it have port number, packing rules etc. can I add some permissions or etc for Kaspersky .
I tested it. app running release mode. and it connecting / reading logs. After I tested debug mode , it is not run.

please do you have idea?

package rules permissions

It maybe related to an unconfirmed bug from b4j 2.8.
https://www.b4x.com/android/forum/threads/error-in-debug-mode-b4j-version-2-8.50495/page-3

I am trying to load an old old project wiith 3.7.1 , similar error.

It happens when :
1. Large project.
2. Breakpoints & bookmarks in handlers/classes (except the main thread)
3. Run in debug mode , debug will not start ( Not every time)
4. Run in release mode , OK.
5. After clear all breakpoints, runs well in debug mode.


You can try to clear all breakpoints .

Updte : It seems that VirtualMachineArgs setting affect it. When VirtualMachineArgs is small and breakpoints are set , this happens more offen.

example :
#VirtualMachineArgs: -Xms224m -Xmx224m with breakpoint : not working
#VirtualMachineArgs: -Xms224m -Xmx224m without breakpoint : working sometimes
Click to expand...
 
I delete some bookmarks and some berakpoint.
Now; its works. maybe my project is large (17mb >> release.jar file)
this is very annoying. IDE never worked on Debug mode for 1 day.
@Erel I'm afraid of the collapse of my project that you worked for months.
What are your suggestions or solutions?

Bookmarks or breakpoints? Breakpoints can make a difference in some edge cases.

may you explane to me?

Today working with my app, I get same error. I last code in "xlsHATA" module. I deleted bookmarks in modele, after code runs..
 
Erel said:
A breakpoint in a sub causes the debugger to choose a different and more complicated execution pipeline. I cannot say what causes this error without a deeper investigation. It might be related to code in process_globals that shouldn't be there.

did you test my app for error?
 
Erel said:
No. I understood that you got it working. If not then upload the project with the breakpoints that cause the error to appear.

Erel again start it. it has a devil inside... I cant understand..

1. I've removed the Dialogs library. I don't think that you need it.
2. I commented the code related to jAutoUpdate as I didn't have the library.
3. I've removed MyResim type. Seems like you declared it in jPicureBox as well (maybe somewhere else).

I've ran it 5 times, with and without breakpoints, and wasn't able to reproduce this issue.
 
Yes, I worked my laptop at weekend. İts same saw same result.
Laptop is win10 & has not virus app, its like same my workpc.

I searched problems.
I removed myresim and etc for clean code like you.
After Isaw 2 diffrent version of JAVA. And deleted all java versions.
Again I loaded latest 1.8.201 version.
After app runs with 2-3 hour .

Today; for work PC, Deleted all JAVA version and re-load latest version of JAVA.
Now works it. I keep watching code.
Hopefully this is just the problem.

Is it a problem to have more than one java version installed?
