User with no role generates an error
------------------------------------
Key: JBPORTAL-190
URL: http://jira.jboss.com/jira/browse/JBPORTAL-190
Project: JBoss Portal
Type: Bug
Components: Portal Core
Versions: 2.0 Beta
Reporter: Thomas Heute
Assigned to: Thomas Heute
Fix For: 2.0 Beta
If a user is in no role, the following exception happens:
java.lang.NullPointerException
at java.util.Arrays.mergeSort(Arrays.java:1152)
at java.util.Arrays.sort(Arrays.java:1079)
at
org.apache.catalina.realm.GenericPrincipal.<init>(GenericPrincipal.java:77)

a:342)
We need either to make sure a user is in a default immutable role, or that a
user can have no role (but does not crash).
For now, portlet.xml must contain a default role for the user portlet:
<init-param>
<description>Default role of registered users</description>
<name>defaultRole</name>
<value>Users</value>
</init-param>
In this case "Users" must be an existing name of role in the database.
