B4J Question JavaObject.InitializeStatic throws java.lang.ClassNotFoundException in Release Mode but not in Debug Mode

[Tobias Leininger]

This code creates the following error in Release Mode but not in Debug Mode:

Error:
java.lang.ClassNotFoundException: org$bytedeco$javacv$Frame

(The jar files are included in the Main Module with #AdditionalJar)

Sub Class_Globals
    Private Frame As JavaObject
End Sub

Public Sub Initialize
    Frame.InitializeStatic("org.bytedeco.javacv.Frame")
End Sub

It's probably a noob error but any ideas what I'm doing wrong here?
It works perfectly fine in Debug Mode.

Full Error:
java.lang.ClassNotFoundException: org$bytedeco$javacv$Frame

Frame.InitializeStatic("org.bytedeco.javacv.Frame")

You are missing an Import for org.bytedeco.javacv.Frame

Add the jar with #AdditionalJar:

 

[Tobias Leininger]

But it is there (added with #AdditionalJar) and works in Debug Mode?

 

[DonManfred]

I never use debug-mode, i can´t give any answer here.

Based on the error i would say a dependency is missing.

Check the dependencies here; there are a lot

https://repo1.maven.org/maven2/org/bytedeco/javacv/1.5.4/javacv-1.5.4.pom

 

[Tobias Leininger]

I would think so too, but it's included and works in Debug Mode but not in Release Mode for some reason.

I'm also confused as it shows $ instead of . in the error message:
org$bytedeco$javacv$Frame vs org.bytedeco.javacv.Frame

Does it work with Java 8? Might be related to the modules system introduced in Java 9.

 

[Tobias Leininger]

So I tried many different versions and got it working by only including some of the libraries.

I'm not really familiar with Java, but it looks like they load the platform specific libraries on runtime in JavaCV and that somehow doesn't work correctly.
Now I've only included the library for one platform directly for each dependency and that works.

What is the difference in Debug Mode vs. Release Mode related to included JARs that makes the behavior so different between the two?

Not enough information to say.
