Log4j not printing the stacktrace for exception

I've noticed interesting behavior in the server logs on jdk 8. There was an exception without stack trace. After small research I have found that hotspot may apply some optimization to exceptions that are thrown too frequent, it simply trim stack trace) So I scrolled to the first occurrences of the exception and found my stack trace. Here is oracle docs describing it:

and you can disable it with -XX:-OmitStackTraceInFastThrow
