Invocation count overflow when profiling

When profiling a program, Visualvm gives a methods invocation count. However that count seems to be stored in an int and thus overflows at 2^31. The invocation count approaches 2^31 and when reaching it the corresponding method just disappears from the list of methods. (probably that list only shows methods that got invoked > 0 times) When waiting for long enough it eventually reaches positive numbers again.

Of course the obvious solution is to store the invocation count as long.
The problem occurred with version 1.4.1 in Intellij 2018.1 .

Start by reproducing profiling with a method invocation count approaching 2^31, then trace where that count is stored and how methods with non-positive counts are filtered from the list. Done means invocation counts continue increasing past 2^31 and the profiled method remains visible.
