After a upgrade from RTC 3.11 to 4.0 the following error appears after 30-120 minutes.

https://rational:9443/ccm/web/_style/?exclude=A&include=com.ibm.team.rtc.web.ui.internal.DashboardPage.js&ss=1zXZ&_proxyURL=%2Fccm&locale=en

--> this requests ends up in a error 500: 

java.lang.NullPointerException
	net.jazz.ajax.model.Sprite.writeCSS(Sprite.java:125)
	net.jazz.ajax.model.StyleSheet.rewriteUrls(StyleSheet.java:224)

	com.ibm.team.repository.server.servletbridge.BridgeFilter.doFilter(BridgeFilter.java:154)
After this the layout of the CCM-Website-Layout is destroyed but full accessible. It happens in both: 32 & 64 Bit.

Is there any solution?


edit: i've found a temporary solution:

related to this workitem : https://jazz.net/jazz/web/projects/Jazz%20Foundation#action=com.ibm.team.workitem.viewWorkItem&id=216290 i found a workaround.

setup your dns configuration to point this dns-adresses to 127.0.0.1

    net.jazz.web.ui
    net.jazz.web.ui.localdomain
    net.jazz.web.app
    net.jazz.web.app.localdomain
    com.ibm.team.dashboard.web
    com.ibm.team.dashboard.web.loc aldomain
    com.ibm.team.process.web
    com.ibm.team.process.web.local domain
    com.ibm.asq.common.web
    com.ibm.asq.common.web.localdo main
    net.jazz.web.ensemble
    net.jazz.web.ensemble.localdom ain
    com.ibm.team.dashboard.viewlet s.web
    com.ibm.team.dashboard.viewlet s.web.localdomain
    com.ibm.team.rtc.web
    com.ibm.team.rtc.web.localdoma in

i know...it's not a nice solution but it will work until 4.0.1 or 4.0.0.2 is delivered. my server is running 48hours with no npe.

thanks randy for letting me know this issue.

yesterday i was able to reproduce the error under sles10-linux.
could it be possible, that the problem is because the hostname is not full-qualified?
