First we thought that using Spring in the project would make the issue happen. So, we removed Spring from the project since every time we instantiated a ClasspathXmlApplicationContext or an AnnotationConfigApplicationContext the issue would happen.

We removed Spring altogether but now the issue just "happened" today again.

Yesterday I've deployed a jnlp in production using the ant tasks, and the app was fine. Today the same build gave me this error. I'll try to post a sample code in github to provide more information. But for now, I hope it's a know issue with a known workaround...
