示例1: main
import sun.hotspot.WhiteBox; //导入方法依赖的package包/类
public static void main(String args[]) throws Exception {
WhiteBox wb = WhiteBox.getWhiteBox();
long reserveSize = 256 * 1024;
long addr;
ProcessBuilder pb = new ProcessBuilder();
OutputAnalyzer output;
// Grab my own PID
String pid = Long.toString(ProcessTools.getProcessId());
addr = wb.NMTReserveMemory(reserveSize);
// Check for reserved
pb.command(new String[] { JDKToolFinder.getJDKTool("jcmd"), pid, "VM.native_memory", "scale=KB"});
