After deploying the newest mifos.war from the g-release branch (for example https://ci.mifos.org/hudson/job/head-g-release-archive/110/org.mifos$mifos-war/artifact/org.mifos/mifos-war/1.9-SNAPSHOT/mifos.war) the server starts without any exceptions, but after logging in there is a blank page.
I believe this is related to the recent REST API changes.
Yes, this was related to REST API spring security changes, it is fixed in g-maint (aab8e844ec6ebd9ad5c72839951a706158d309d5).
Verified on 04.10.2011
There is no problem to log in on the latest war (hudson-head-g-release-archive-130).
