Sun app server 9 - IllegalStateException at getAttributeNames

[Henrique Ordine]

Hi everyone,

My sun one sever instance keeps logging the Severe message:

Exception invoking method getSession java.lang.IllegalStateException

The logger is com.sun.org.apache.commons.modeler.BaseModelMBean

Should I be concerned at all? Could this cause any fatal problems?

Here is some of the stack trace:

PWC2779: getAttributeNames: Session already invalidated at org.apache.catalina.session.StandardSession.getAttributeNames(StandardSession.java:1188) at org.apache.catalina.session.StandardSessionFacade.getAttributeNames(StandardSessionFacade.java:153) at org.apache.catalina.session.ManagerBase.getSession(ManagerBase.java:1380) at sun.reflect.GeneratedMethodAccessor105.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:585) at com.sun.org.apache.commons.modeler.BaseModelMBean.invoke(BaseModelMBean.java:503) at com.sun.jmx.mbeanserver.DynamicMetaDataImpl.invoke(DynamicMetaDataImpl.java:213) at com.sun.jmx.mbeanserver.MetaDataImpl.invoke(MetaDataImpl.java:220) at
