For example, there is a compiler which compiles your Java code into machine code, and that code has to go into memory somewhere. Also, the Garbage Collector has some overhead of managing the heap itself, and that information cannot go into the heap. (Okay, some of it can, but some cannot.) Native libraries do not use the Java heap. The JVM itself uses the Java heap for some things, but off-heap memory for other things. I've seen JVM processes that use ~50% non-heap memory. Those are extreme cases, but it does happen. >> *OS Details:* > > This mailing lists drops images.
