java.lang.ArrayIndexOutOfBoundsException | But why?

[Deleted user]

Sometimes we have a "java.lang.ArrayIndexOutOfBoundsException" in our Jira AND Confluence System

Jira: v4.2.4-b591#591

Confliuence: 3.4.9

In the catalina.out of each system i found this:

2011-08-15 17:11:10,382 http-127.0.0.1-8080-9 ERROR [500ErrorPage.jsp] Exception caught in 500 page null

The user get a a Error Message "Oops - an Error has occurred" with an information like java.lang.ArrayIndexOutOfBoundsException

For information, we have an own SSO Systemconector which gets every 15 min a new csv file with the user information. For testing i have disabled the copy of this file to the jira and confluence system. Maybe it is an error with the file state of read write while the file is getting renew.

Has anybody an idea, what s the reason of this error?!

I think you've answered your own question - your SSO synchronisation is not working well enough. Confluence and Jira are picking up a user name but no permissions for it. You'll need to fix the synchronisation before it'll work. I don't really know where to point you at for fixing it though.

I dont know if it is really the synchronisation. Because of this i have deactivated the sync. Now i m waiting for the error, if it will happen again or not. If it will not happen, i now the reason, but if it happens again, i need an answer for where i have to look for this error.
