We all make errors, but some errors seem so ridiculous we wonder how anyone, let alone we ourselves, could have done such a thing.
This is, of course, easy to notice only after the fact. Below, I describe a series of such errors which we recently made
in one of our applications. What makes it interesting is that initial symptoms indicated a completely different kind
of problem than the one actually present.

CPU time and memory are the two primary resources every performance-sensitive application needs to use wisely. Java is now the language
of choice for many such systems. While most developers have at least basic understanding of computational complexity, I believe that few,
especially among those who primarily use Virtual-Machine based languages such as Java, understand well how their applications manage memory.
This is not only a very interesting topic in itself, but can also help in improving performance of Java applications or in understanding
better the behavior of common Java-based databases such as Apache Cassandra.
