We present an analysis of the memory usage for six of the Java programs in the SPECjvm98 benchmark suite. Most of the programs are real-world applications with high demands on the memory system. For each program, we measured as much low level data as possible, including age and size distribution, type distribution, thread-local objects, and the overhead of object alignment. Among other things, we found that non-pointer data usually represents more than 50% of the allocated space for instance objects, that Java objects are fairly small, and that a large fraction of objects is never accessible outside the thread that allocated it.
