It looks like there is an exception being thrown during the initialization of the com.example.nativedemo.config.ApplicationConfig servlet. The specific exception is a java.lang.ExceptionInInitializerError which means that an exception was thrown during the initialization of a static variable or a static initializer block. It seems like there is an issue with the FormParamValueParamProvider class which is used by Jersey to handle form parameters in the request body. The error could be caused by an issue with the configuration or setup of Jersey or the Spring Boot application. It would be helpful to look at the ApplicationConfig class and the FormParamValueParamProvider class to see if there is any issue with the configuration or setup of the application. Additionally, it might be useful to check if there are any compatibility issues between Spring Boot 3.0.1, Spring Boot Jersey Starter, GraalVM 22.3, Java 17 & 19.
