What needs improvement with Parasoft Service Virtualization?

There is not much more room in areas of improvement, unlike a Portal-based Virtualization. I didn't see any updates coming in next releases. Except, sometime we face proxy exception issues, which is already reported to Supported Team. Overall, It's trusted and working nice as expected.

JMS Queue Monitoring: When deploying the TIBCO JMS monitor, we saw an approximately 50% failure rate in detecting the desired event. This is probably due to the asynchronous nature of the event itself, and the natural background flow of other events. Though this feature sounds cool, we had to work around it and create a different solution.
