Subject [jira] Created: (JSPWIKI-116) UserManager generates NPE in certain cases
Date Fri, 28 Dec 2007 15:43:43 GMT
UserManager generates NPE in certain cases

                 Key: JSPWIKI-116
             Project: JSPWiki
          Issue Type: Bug
          Components: Authentication&Authorization
    Affects Versions: 2.6.0, 2.6.1
         Environment: OS X 10.5.1, Tomcat 6.0.14
            Reporter: Andrew Jaquith
            Assignee: Andrew Jaquith
             Fix For: 2.6.1

Under certain circumstances, calls to UserManager.getUserDatabase() are made before the user
database is actually initialized, resulting in NPEs. To resolve, we simply need to replace
internal references to m_userDatabase with getUserDatabase(), which will lazily initialize
the database if it has not already happened.

Not sure why we didn't spot this before, but it bit me in the a** yesterday.
