Hello Vaadin team,
We are using Websphere Application Server 8.5 with Liferay 6.2 and Vaadin 7.7.8 portlets.
Currently, we are facing the problem with HUNG threads in the production.
We decided to enable asserts for com.vaadin.server and its subpackages and we got the error java.lang.AssertionError: “Cannot change the lock from one instance to another”.
javax.portlet.PortletException: com.vaadin.server.ServiceException: java.lang.AssertionError: Cannot change the lock from one instance to another

How to replicate the problem
- enable asserts for com.vaadin.server and its subpackages
- add the same vaadin portlet 2x to the same Liferay page
- try to load the Liferay page. You should get java.lang.AssertionError.
This can be replicated on Tomcat as well.
With disabled asserts we got HUNG threads on Websphere.
Cause
Locking mechanism relies on unique portlet name which is used in a key in a map.
This is not true in case of two instances of the same portlet.
Solution
Our Solution was to use PortletSession.PORTLET_SCOPE for VaadinSession.
We had to use customized VaadinPortletService.
With this solution we do not face any HUNG threads anymore.
Is this a bug introduced in #7184 Vaadin 7.6.0?
According to the Vaadin release-notes 7.6.0 there was a change #7184 - Store VaadinSession as APPLICATION_SCOPE in portals -
https://github.com/vaadin/framework/issues/7184
Our Fix
public class CustomVaadinPortletService extends VaadinPortletService {
...
@Override
protected void writeToHttpSession(WrappedSession wrappedSession,
VaadinSession session) {
getWrappedPortletSession(wrappedSession).setAttribute(
getSessionAttributeName(), session,
PortletSession.PORTLET_SCOPE);
}
@Override
protected VaadinSession readFromHttpSession(WrappedSession wrappedSession) {
return (VaadinSession) getWrappedPortletSession(wrappedSession)
.getAttribute(getSessionAttributeName(),
PortletSession.PORTLET_SCOPE);
}
@Override
protected void removeFromHttpSession(WrappedSession wrappedSession) {
getWrappedPortletSession(wrappedSession).removeAttribute(
getSessionAttributeName(), PortletSession.PORTLET_SCOPE);
}
private WrappedPortletSession getWrappedPortletSession(WrappedSession wrappedSession) {
return (WrappedPortletSession) wrappedSession;
}
}
// Customize VaadinPortlet(override createPortletService method) to use CustomVaadinPortletService
// Use customized VaadinPortlet for portlet-class in portlet.xml
