Thread "server.startup : 0" may be hung

Thread "server.startup : 0" may be hung

I have a web application using springframework(version 2.5.6), openJPA(JPA
implementation) and atomikos(JTA implementation). The application WAR file
was created by maven and had the WEB-INF/lib folder which included all the
libraries. The application will be deployed in IBM Websphere Application
Sever 6.1. There was no issue until I removed the lib folder in the WAR
package and replaced it with the shared library(which includes all the
libraries in the lib folder in the WAR). The issue is that the application
server took more than 10 minutes(normal case should be less then 2
minutes) to get started. The issue is intermittent. The following logs
were from the application server's SystemOut.log:

Anyone has any idea?
Appreciate your help!
