Hi, Alex from OverOps here. We've created the "Bullshifier" internally to stress test edge cases with our own monitoring tool (http://www.overops.com).

Whenever an exception or a logged error / warning happens in production, it shows you the complete source code leading to it, and the full variable state across the entire call stack.

Using Java Bullshifier, we're able to generate random applications with call stacks that can go thousands of frames deep and other quirky behaviors. This helps us make sure the overhead is unnoticed, even in the most extreme cases.

Would be happy to answer any questions.
