I have a problem upgrading to GWT 2.8.1 from 2.7.0.
Changed version of gwt in pom. Checked dependencies, updated them. Changed
servlet-api version to 3.1.0.
When I try to run application code server has an error:
HTTP ERROR: 500
Problem accessing /. Reason:
java.lang.NoSuchMethodError:
javax.servlet.http.HttpServletResponse.getHeader(Ljava/lang/String;)Ljava/lang/String;

>From what I got, I understand that Code server trying to use wrong version
of servlet-api. I see in my classpath servlet-api version 2.3, but I
removed all other servlet-api versions in every dependency has it.
I would glad to look in your recommendations.
