I have a very strange problem which I can't figure out by myself. I have a JSF application that I'm developing and it's deployed on a Tomcat server at client site. It works just fine. However, after a few days, it starts to behave very weird, and I'm getting a lot of exceptions such as the following in the log:
SEVERE: Error Rendering View[/index.xhtml]
com.sun.facelets.tag.TagAttributeException: /menu.xhtml @21,53 test="${!empty bean.menuItems}" /menu.xhtml @21,53 test="${!empty bean.menuItems}": Error reading 'menuItems' on type com.blabla.bean.ApplicationBean
at com.sun.facelets.tag.TagAttribute.getObject(TagAttribute.java:235)
at com.sun.facelets.tag.TagAttribute.getBoolean(TagAttribute.java:79)
at com.sun.facelets.tag.jstl.core.IfHandler.apply(IfHandler.java:49)
at com.sun.facelets.tag.CompositeFaceletHandler.apply(CompositeFaceletHandler.java:47)
.....
Please note that bean refers to an object of type com.blabla.bean.ApplicationBean
which is an application-scoped bean. The above xhtml code is inside a c:if, that's why I use the $ notation. As mentioned, the application runs just fine for the first 2-3 days, it is only after a few days when these exceptions occur in the log, and they are only related to the only bean that's in application scope. Normally, when I get such exceptions I check if the getter for the 'menuItems' field is in the bean, but it is there and if it wasn't, the application would not work at all and not work fine for 2 days and then crash.
I also encounter exceptions related to the custom resource bundle that I have in my application:
Caused by: javax.faces.FacesException: Could not load resource bundle for name 'messages': Can't find bundle for base name com.blabla.messages.CustomResourceBundle, locale de
Again, the bundle was loaded during the first 2-3 days of the application life, but then this exception occurs all of a sudden.
Has anybody encountered a similar situation? Can anybody point me in the right direction as to where to look for the problem, since I'm completely out of ideas here.
Thank you in advance.
