急！郁闷阿，jacob调用COM组件导致内存溢出

[wuboy2000]

最近公司做项目，需要用我们的Java程序调用第三方的指纹考勤COM组件。
我采用Jacob组件来实现，能够得到COM组件的对象了，但是在调用相应的方法时，突然抛出异常，大概是内存溢出的错误。代码如下：
=========================================================================================================
import com.jacob.activeX.*;
import com.jacob.com.*;

public class Test {
private Dispatch dispatch;
private ActiveXComponent com;

public static void main(String[] args){
System.out.println(Runtime.getRuntime().freeMemory());
System.out.println(Runtime.getRuntime().totalMemory());
Test test=new Test();

ComThread.InitSTA();
test.com=new ActiveXComponent("YsAc.YsApoCheck");
test.dispatch=test.com.getObject();

Variant v=Dispatch.call(test.dispatch, "ApothecaryCheck");

ComThread.Release();
}

}
=========================================================================================================



当程序运行到语句“Variant v=Dispatch.call(test.dispatch, "ApothecaryCheck");”时，系统异常，信息如下：
=========================================================================================================

我已经设置了-Xmn100M -Xms200M -Xmx300M参数，并且从上面的运行结果看到可用内存也有小200M。
郁闷，望哪位高人给指点下阿？！
