Number of invocations and completes aren't equal.

When looking at this execution trace. When using 'grep' it shows that there are 123337 instruction execution events from those 45400 are '$complete$', but $invoke$ is called 45401, meaning one invocations is missing an complete.

This can/should happen when some method invocation does not return back to its call site. On a quick investigation it seems that the guilty invoke, ie. the 45401st invoke without a complete event is a com/intellij/rt method. I am yet to determine the exact cause -- stay tuned.
