Hello Burak,
How are you measuring the memory used?
Could it be that the 200MB you are seeing are the -Xmx192m (same as
-Xms) JVM settings for the heap and reported by an OS tool like top?
Will the application run (no outofmemoryerror) if you lower these values
(that would require lowering -XX:MaxPermSize to something like a 1/3rd
of the heap size)?
cheers,
-Alexis
