java.lang.VerifyError

Vaadin 6 / 7 / 8

Hi guys,

I am getting this error when deploying to a Tomcat 7 server and I can’t find a way to fix it.

java.lang.VerifyError: (class: com/vaadin/server/Page, method: getJavaScript signature: ()Lcom/vaadin/ui/JavaScript;) Incompatible argument to function

com.vaadin.ui.UI.<init>(UI.java:155)
com.vaadin.ui.UI.<init>(UI.java:185)
dp.webadmin.WebAdminMainUI.<init>(WebAdminMainUI.java:40)

Any suggestions?

Thanks,
Francesco
