一、示例代码
public class JavaMethodAreaOOM {
static class OOMObject{
}
public static void main(String[] args) {
while (true) {
Enhancer enhancer = new Enhancer();
enhancer.setSuperclass(OOMObject.class);
enhancer.setUseCache(false);
enhancer.setCallback(new MethodInterceptor() {
@Override
public Object intercept(Object obj, Method method, Object[] args, MethodProxy proxy) throws Throwable {
return proxy.invoke(obj, args);
}
});
enhancer.create();
}
}
}
二、VM args
-XX:MaxMetaspaceSize=10M
