我升级到Mojarra JSF 2.2.1(从2.1.22开始),从那时起我的每个请求都在控制台中出现异常:

GRAVE: JSF1094: Could not decode flash data from incoming cookie value /?.  
Processing will continue, but the flash is unavailable for this request.
com.sun.faces.lifecycle.InvokeApplicationPhase execute

当我没有使用闪存范围时,请求成功完成.但是,因为我正在使用此范围FacesMessages,如果我在此处输入消息,我有一个NullPointerException并且导航流程被中断:

GRAVE: El Servlet.service() para servlet Faces Servlet lanzó una excepción
java.lang.NullPointerException
