For those of you trying to start heavy-loaded application, with a lot of INFO level logging to console. Be aware Eclipse console printer can be confused by amount of data to print and hang Eclipse for a long time, while server actually will be started and can be accessed via browser.

This problem happened to me and took me quite a while to figure out what's happening. I'm running Eclipse Mars and Tomcat 7. In my case app was trying to print all singleton bean names to console, about several thousand bean names thus Eclipse was going crazy.

org.springframework.beans.factory.support.DefaultListableBeanFactory#preInstantiateSingletons

    if (this.logger.isInfoEnabled()) {
       this.logger.info("Pre-instantiating singletons in " + this);
    }

Give it a try, put the app logging level=ERROR. Hopefully this will help someone.
