Hi,
After upgrading to the version 7.3.1 of Vaadin and the 1.0.0.beta2 version of the vaadin-cdi component (as advised by the Vaadin team) I’m getting the following ClassCastException in WebSphere (although it’s working fine in TomEE) :

I’ve tried to change the classloading policy to PARENT_LAST without any luck.
Can someone acknowledge that the vaadin-cdi add-on was tested on WebSphere 8.5 ?
Besides that does someone know what could cause the error and how to resolve it ?
Thank you in advance.
Kind regards,
Richard Aalten
