Null Pointer Exception When Initializing

So,

I installed latest openfire 4.8.3 and now I want to initialize it by going to localhost:9090 and I see Choose a language. I select English, then I click next and I am asked to select domain name and encryption algorythm. I leave the default values and I click next and I see this exception:

Caused by:
java.lang.NullPointerException: Cannot invoke "String.equals(Object)" because "oldAlg" is null
	at org.jivesoftware.util.JiveGlobals.setupPropertyEncryptionAlgorithm(JiveGlobals.java:1112)
	at org.jivesoftware.openfire.admin.setup.setup_002dhost_002dsettings_jsp._jspService(setup_002dhost_002dsettings_jsp.java:265)
	at org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:70)
	at javax.servlet.http.HttpServlet.service(HttpServlet.java:590)

What is the problem?

That seems to be some kind of bug in the setup page. Thanks for reporting this. I’ve raised a ticket for this issue: [OF-2868] - Ignite Realtime Jira
