Observing memory usage in Task Manager is not an accurate measure of how a Java app is using memory. The memory Task Manager reports includes both the memory that the JVM uses to do its job and the heap space used (the Java app's data).

The default settings for the heap in run.bat allow for the JVM to continually ask for more memory for the heap, up to 512MB.

To better understand how the Java heap works, including garbage collection, see my presentation at http://www.cecmg.de/doc/tagung_2007/agenda07/24-mai/2b3-peter-johnson/index.html
