This is normal and expected. The numbers shown in your JSP and adjusted via the -Xmx and -Xms arguments are the JVM heap only. The JVM itself contains several other memory areas (the stack, the symbol table, etc.), although they are typically smaller than the heap. Then the operating system (this is true for all OS's, not just windows) adds overhead for scheduling, memory allocation, thread managements, etc. The task manager on windows shows the overall footprint as seen by the operating system: that includes all the above memory-consuming tasks on top of the JVM's heap. You would always expect it to be higher than the heap itself.
