在Jrockit中旧集合的扫描切换过程中，我面临着长时间暂停的问题，这使得我的应用程序在几秒钟内没有响应

Jrockit版本：R28.3.12-8

配置：

JAVA_OPTS="-Xms10G -Xmx10G -Xns:2g -Xgc:pausetime -XpauseTarget:201 
-XXgcTrigger=40 -Xgc:gencon -XXkeepAreaRatio:50 -XXcompactRatio:10 
-XX:NurseryPartsLimit=0 -Xverbose:memory -Xverbose:memdbg -Xverbose:gcreport 
-Xverbose:compaction -Xverbose:gcpause -Xverbosetimestamp"

日志：

我的应用程序通常需要不到1秒的时间来完成一个旧集合，我能看到的唯一区别是，在正常集合期间创建托儿所时，它在第一次创建时被分配2GB，而在长期运行中，一个托儿所被分配2GB是两部分

正常：
