According to Wired Java is experiencing a renaissance of sorts: http://www.wired.com/wiredenterprise/2013/09/oracle_java/
Just like Coldfusion, many people have been saying Java is so 1995 but since Twitter showed how well Java scales compared to the woeful RoR it is seeing a renaissance. And since Railo is a Java framework that speeds development I have a feeling we will being seeing it experience a similar renaissance in the near future.
