A web application bundled with its own Jersey implementation (which is 1.x) crashes admin console after server restart. The application has glassfish-web.xml config file for classloading settings (delegate=false).
Exception is :
Looking at the verbose classloading output (-verbose:classes), admin console application grab Jersey 1.x classes from deployed application in applications folder. Manually deleting jersey 1.x jar from application's folder solves the exception and admin console starts. But is it not possible to deploy a Jersey 1.x application to Glassfish4?
