I´m using my org project jar (called org-project-execution.jar) which includes a class called com.ctc.wstx.shaded.msv_core.reader.GrammarReaderController and import it in my Java program.
The code builds but when it calls the method “org.project.execution.Executor.execute(inputStream, inputLength)”` the following Error happens:

For some reason java tries to load a com/sun/msv/reader/GrammarReaderController instead of the com.ctc.wstx.shaded.msv_core.reader.GrammarReaderController included in the project jar. Then I tried including a msv-core-2022.7-jar-with-dependencies.jar that has com/sun/msv/reader/GrammarReaderController in it, build the project, but the code still throws the same Runtime error. How is the method .execute not finding the GrammarReaderController in the right import and tries to find in some other package?
