Processing Dirty Regions -> AbstractInterceptorDrivenBeanDefinitionDecorator

I use the latest Springsource ToolSuite (STS) version 2.5.0 (based on Eclipse) and on startup I get this error message:

An internal error occurred during: "Processing Dirty Regions".
org/springframework/aop/config/AbstractInterceptorDrivenBeanDefinitionDecorator

The error occurs by opening my app-config.xml

An internal error occurred during: "Initialize Beans Graph 'app-config.xml'".
org/springframework/aop/config/AbstractInterceptorDrivenBeanDefinitionDecorator

The content of it:

</bean>

<!-- Configures Spring MVC -->

Does anyone know how I can solve this problem?

Thank you in advance & Best Regards.

Looks like a STS bug. You should never see this message otherwise.
