In some places it makes decisions based on the queue length length alone without looking at the invocation counters. That can cause a starvation effect. For example when running in a C2-only mode it may delay profiling in the interpreter if the C2 queue is too long. The solution to this is detect "old" methods (that is method that have been used a lot) and force putting them into the queue and let the queue prioritization deal with it.
