Java AppletRelaunch由于健康

我有一个Web应用程序,在其生命周期内创建/销毁几个小程序.在创建新applet时,JVM会定期启动第二个实例.applet共享各种内存结构,因此JVM重新启动会导致整个应用程序出现故障.

这是我唯一的线索.在控制台中,这是applet启动导致新JVM启动时所写的内容:

与此相比,在正常的applet启动期间写入控制台:

security: SSV validation:
    running: 1.7.0_51
    requested: null
    range: null
    javaVersionParam: null
    Rule Set version: null
network: Created version ID: 1.7.0.51
network: Created version ID: 1.7.0.51
security: continue with running version
network: Created version ID: 1.7.0.51
network: Created version ID: 1.7
network: Created version ID: 2.2.51
security:  --- parseCommandLine converted : 
into:
[]

在这一行上,一切都是一样的:

basic: AppletRelaunch due to health

谷歌搜索这给了我什么."健康"是什么意思？我的直觉和重新启动的时间让我觉得它与内存消耗有关,但java.exe总是在200mb以下运行,我尝试使用java_arguments(-Xms256m -Xmx1g -Xss256k)增加内存限制无济于事.

关于什么可能导致重新启动的任何想法？有没有办法从HotSpot JVM获取更多信息,以找出哪些特定的"健康"检查失败？
