Yes sounds like the ErraiBus holds a reference to your class even though you don't use it anymore. Its similar to GWT EventBus that usually exists as a singleton in your app and if you don't deregister your handler you prevent garbage collection.
As Errai is pretty complex and I never used it I can't really tell you how to solve the issue other than consult their documentation or ask on a specific Errai forum/group/irc-chat. -- J. -- You received this message because you are subscribed to the Google Groups "GWT Users" group.
