I believe this to be a -um- "valid" claim. According to the reports that I have heard, the Java (Sun, which version?) garbage collector would collect garbage internally, but would never return the allocated / collected space back to the operating system. This would cause the program to develop a very slow "leak". I don't know how serious this ever became (or, actually, even whether this was true) but this was the claim. So, in some sense, it never did collect and free any memory, although the program was able to re-use it.
