When I run maven-jetty-plugin, I run next command:
mvn -DMAVEN_OPTS="-Xmx1024m -Xms512m" -Djetty.port=8080 jetty:run
but when I try to output free heap size with
Long heapFreeSize = Runtime.getRuntime().freeMemory();
It always outputs something about about 30000000.
I suppose it s size in bytes, so about 30 megabytes.
Why then free heap memory did not increase?
