Bug? Error in Debug mode B4J Version 2.8

[Swissmade]

Hi Erel,
Is there a possibility to use 2.8 with my Debug problems or is it the way I write the code??
Back to 2.5 I see many very nice options I like to use with 2.8.
The program you have seen will getting more and more complex and bigger.
License plate reading will also a part of this.

Many thanks for you good help.

Working with B4J 2.5 is still have problems in Debug mode.
Same I have seen in B4J 2.8.
Start the application I get following Error.
Start again the error is away most of the tima and the Program is starting.
Seems that the Debugger have some speed problems. This is happening when I change or add some code.
Processing timeout is set to 60 seconds.

Hope somebody has a solutin for this.
Thanks

[Erel]

It is worth checking the IDE logs as explained here: https://www.b4x.com/android/forum/threads/intermittent-error-message.9047/#post-50478

IDE logs

Thanks Erel,
Have the log.
I hope you can help me out here.

 

[Erel]

Seems like you are not using the modified jRapidDebug.jar I you sent in the past which should (partially) fix this issue.

 

[Swissmade]

using the modified jRapidDebug.jar

Just installed the version 2.5
Ok will install this thanks.

 

[Swissmade]

Installing B4J 2.8 again and the Debugger Fix give me again the same issue.
Breakpoints not working and not seen when I start with Breakpoints on.
Place them later again work sometimes.

 

[Swissmade]

Running the code the Debbuger sometimes is stop by a Breakpoint not exist.
This without changing any code.

 

[Swissmade]

I have the Idea, that somehow when I start the Program old code is still in memory.
Leave the IDE and start again the code is running with Debug.
Is there a option for the Debugger to force full compilation or is this always done.
Running B4J 2.8 with the modified jRapidDebug.jar

 

[Swissmade]

Reinstall B4J 2.5 and I have less problems then with 2.8.
Will see what is happening.

 

[Erel]

Is there a option for the Debugger to force full compilation or is this always done

It always forces a full compilation in B4J.

 

[Swissmade]

It always forces a full compilation in B4J.

Maybe a Memory issue with Big Programs.
Ok Then I have to stay with 2.5 for not having so much Debug problems.
Bad 2.8 has some very nice options I like to use.

 

[Swissmade]

I really get the idea it is a memory issue.
Get sometimes the same error with 2.5 and when I close B4J and Start it again the Problem is away for a while.
My Computer is not too fast. Still working with a Core 2 Quad and Windows 7.

 

[Swissmade]

Maybe found something.
When I get the Error I switch to release mode without running and switch it back to debug mode.
The error is away for a while.
This in B4J 2.5 and B4J 2.8.
Maybe this can help.

Hi Erel
Sorry to use your time on this thread but I think the Problem was on my PC.
I always was thinking this is a Memory problem and it was but in an other way I expected.
I never watch my memory in my PC because the PC is function normal and give me not any error.
This week I have seen, that I only have 7GB instead of 8GB in my PC.
Testing the Memory there was not any problem.
After set the Bios, I never touch for a while, to Default settings I get 8GB back.
Reinstall B4J 2.8 I don't see any errors anymore.
I will watch this and will let you know if something else is going on.

Thanks again for your very good support.
Cheers
Swissmade

 

[Erel]

Interesting. Lets see whether this error returns. I wasn't able to reproduce it here.

 

[Swissmade]

I wasn't able to reproduce it here.

I have seen this error again but not so much as before.
Now I go to test this with the Debugger fix.
I will let you know.
Many thanks again.

 

[Swissmade]

Now I go to test this with the Debugger fix.

What I see is, that when I start with Breakpoints, the Breakpoints are not seen and ignored.
New added Breakpoints are seen.

Start without Breakpoints and Add them when the Program is running, Breakpoints are seen.

Maybe you can work with this to find a solution.
If you like, I can arrange a Team-viewer session and you can see it what I mean.
