The class exists i checked it earlier. When i run my test code in IDE it worked.

(Also https://groups.google.com/g/snakeyaml-core/c/rrEM8Plxd6Q is the same problem with mine)

Such problems typically arise from classes not being available in
contexts where you expect to have them.

We lack some details here:

The programming language you're using (is it Kotlin?)

Is the data read and written in the same process, or in different processes?

What's the failing situation - is it a .jar file?

If it is a .jar file: Did you unpack it and look if the class is there?
There are multiple ways how a class could be present in the IDE but not
in the jar, e.g. in Eclipse, with the typical Maven-inspired setup,
classes from the test directory are available in the IDE but the jar
build excludes themj.

Programming language is kotlin. I checked the class by decompile the jar, use Class.forName and create a instance of the class. The data read/write is in the same process.

Are class loaders involved?
The same bytecode, loaded through different class loaders, will give
different classes at runtime.
Unfortunately, standard error messages don't typically name the class
loader they are associated with, so you have to use your own diagnostics
to figure that out.
