Hi Scott, The memory leak circumstance was not spotted in Resin 4.0.5 and early 4.0.x versions.
One of the inject path is: * A filter CmsPageFilter dispatch a request to a Jsp page through javax.servlet.RequestDispatcher.forward(request, response) * Jsp page called a BeanMethod custom jsp tag * The jsp tag create a VideoManager through my BeanManager wrapper (MDIObjectFactory) * VideoManager injects a PersonManager * PersonManager injects a PersonController * PersonController injects a DefaultBeanManager and a DefaultBeanReader * DefaultBeanManager and DefaultBeanReader inject a CmsPersistentUnit(@Singleton) * CmsPersistentUnit injects a javax.persistence.EntityManagerFactory (@PersistenceUnit) All those beans except CmsPersistentUnit were dependent scoped (not explicitly annotated) and should be created at its inject point and freed when the parent bean (the jsp page) was destroyed. I list three most frequently bean creation process here. #============handle jsp tag which requires bean creation=================== # this call should be the creation of an @Dependent (thought not explicitly annotated) beans #
