In DevMode, when the browser is refreshed and the module is loaded again, does the prev' one exists in memory?

Because, after several refreshes I sometimes get this error:

19:33:47.995 [ERROR] [xxxxxxx] Out of memory; to increase the amount of memory, use the -Xmx flag at startup (java -Xmx128M ...)

Even though I set the -xmx variable to -Xmx512m. Is there a way to clear to force the devmode to clear the previously loaded app, and start again (without stopping the devmode completely)?
