I'm using jBPM 4.4 and Spring 2.5.6. jBPM calls +org.jbpm.pvm.internal.env.SpringContext.get(Class<T> type)+ to retrieve Spring beans. This method calls +org.springframework.context.ApplicationContext.getBeanNamesForType(type+) everytime to get the bean anme for the class. These calls causes 30 MB memory usage after short runtime with only one user. Nebeans Profiler snapshot: https://dl.dropbox.com/u/342869/SpringContext.png https://dl.dropbox.com/u/342869/SpringContext.png Since +getBeanNamesForType(type+) reads names from the static Spring configuration +SpringContext.get+ should cache the names after reading. I added a simple static +Hashmap+ to SpringContext which saved 25 MB ram. I added a patch for maven module +pvm+ of the jBPM-4.4 sources. A more sophisticated cache solution may be required in other environment with multiple Spring +ApplicationContexts+ in one JVM. - Daniel -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/582960#582960] Start a new discussion in jBPM Development at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
