Serializing principals no longer work in Tomcat 8 #227

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
Serialization does not work when deploying to Tomcat 8.0.21.

Tomcat has removed org.apache.catalina.ha.session.SerializablePrincipal, which 
MSM uses. Serialization fails with the following stack trace:

SEVERE [http-nio-8080-exec-5]

The class was deleted on the 16:th of December 2014 according to this mailing 
list message: http://svn.apache.org/viewvc?view=revision&revision=1645955. It 
is likely that earlier versions of Tomcat also are affected, but I haven't 
tested that. According to the patch, it is no longer needed since 
"GenericPrincipal now implements Serializable".

This has been tested with on:
Mac OS X 10.10.3
Oracle Java 1.8.0_11
Apache Tomcat 8.0.21
memcached-session-manager 1.8.3
memcached-session-manager-tc8 1.8.3
