java - Why StatefulSessionComponent cause a memory leak? -


because of java heap space error did heap dump of java ee 7 program running on wildfly 9 server. used eclipse memory analyser analyse dump. eclipse memory analyser reveals 2 following problems same:

one instance of "org.jboss.as.ejb3.component.stateful.statefulsessioncomponent" loaded "org.jboss.modules.moduleclassloader @ 0xe0130378" occupies 168 975 304 (36,60%) bytes. memory accumulated in 1 instance of "java.util.concurrent.concurrenthashmap$node[]" loaded "".

one instance of "org.jboss.as.ejb3.component.stateful.statefulsessioncomponent" loaded "org.jboss.modules.moduleclassloader @ 0xe0130378" occupies 155 775 312 (33,74%) bytes. memory accumulated in 1 instance of "java.util.concurrent.concurrenthashmap$node[]" loaded "".

i have few stateful ejbs on program. mean ejbs never garbage collected ? idea how solve problem ?

edit

here capture of dominator tree: dominator tree seems class java.util.concurrent.concurrenthashmap$node cause.

scala - 'wrong top statement declaration' when using slick in IntelliJ -

i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
