http://issues.apache.org/bugzilla/show_bug.cgi?id=43840 Summary: Unexpected behaviour when GenericPrincipal is serialized using the SerializablePrincipal in a cluster. Product: Tomcat 6 Version: 6.0.14 Platform: PC OS/Version: Linux Status: NEW Severity: normal Priority: P2 Component: Cluster AssignedTo: [EMAIL PROTECTED] ReportedBy: [EMAIL PROTECTED] The method 'getUserPrincipal()' in the GenericPrincipal class returns itself or a provided Principal if possible. This is also the return value of the request.getUserPrincipal() method. This works fine in a non-clustered environment. However the behaviour of this method changes when the GenericPrincipal is serialized by the SerializablePrincipal class. In the initial node of a cluster the request.getUserPrincipal() method behaves normally. However after the principal is serialized to another node it no longer contains the internal Principal object, so the same method call will now return a different object. I think a solution could be: 1) If there exists an internal userPrincipal AND it is Serializable then serialize it along with the other properties of GenericPrincipal. 2) Recreate it at the other end if it is available in the object stream. In this manner users with custom Principal objects that implement java.io.Serializable will have predictable results from the request.getUserPrincipal method across nodes in a cluster. I'd appreciate your thoughts on this.
