Cannot load provider in a servlet setup with spring #9
Description
Experience an error No provider of PromiseProvider found! when running servlet application with spring.
I guess it may be related to the class loader hierarchy or class loading sequence.
Currently I hack around this by adding a listener to the servlet
<listener>
<listener-class>ServletStartupListener</listener-class>
</listener>
public class ServletStartupListener implements ServletContextListener {
public void contextInitialized(ServletContextEvent sce) {
log.info("Init JAsync");
JAsync.just();
}
}
I think one approach to solve this issue is to lazy load the provider instead of loading it in the static phase at JAsync.class
