Internal Error after clicking on any component

Hi!
I’m getting: Internal error.
Please notify the administrator. Take note of any unsaved data

In server.log I can see:

I’m gettin this error when I want to use app after some time after server restart, for example: restart on morning->internal error on next day or on evening. Clicking on components (on TableSheet Tabs) invoke red label with Internal Error. Sometimes when I refresh page certain amount of times, app is finally fine. One and only safe way to fix this is serve restart and clean server data, tmp, work.

I’m using:
-Vaadin 7.1.10
-jboss5(trying in many variants of jboss5, error still exists)

My vaadin libs are in WEB-INf/libs folder.

I would be thankfull for help.
