A few days ago I had a small epiphany on a simple yet important issue. I was trying to squeeze those last few percents of performance out of JavaRebel and it came to the point where I started optimizing individual hotspots method-by-method.
One of the most common ways to improve execution time of a specific method [...]
For all those spec believers out there: what would you think if I told you that all of the JVM implementations consistently violate the spec for at least one particular instance?
Our story begins on a cold and lonely evening when I discover a bug in JavaRebel in conjunction with Xerces XMLEntityManager. The problem was [...]

Once I got rid of all the obvious bottlenecks and optimizations I fired up the profiler and started searching and destroying ad-hoc hotspots. After some time I got to the point, when the bottleneck was in System.currentTimeMillis().
This deserves some explanation. Since JavaRebel [...]

The funny part is that now the “three months” don’t have any value whatsoever, as the space [...]
