问题:
我有一个J2EE应用程序,对于使用特定数据集的给定任务(生成一些文件),运行非常缓慢。我决定在应用程序上运行visualvm分析器来理解问题的本质。应用程序正在使用最新的Java 8在Widlfly 10上运行。
为了避免配置复杂性,两个PrrPosiver(VisualVM)和MyF飞服务器都在本地运行。
遇到的第一个问题是JVMTI错误62,使用
-Xverify:none
作为jvm参数。
第二个问题(
拦网的那个
)如果在部署和运行应用程序时运行探查器,Wildfly部署扫描程序将抛出如下异常:

如果在没有任何已部署应用程序的情况下运行探查器,VisualVM的探查器将毫无问题地启动;但是,如果尝试在此状态/操作模式下部署应用程序,wildfly扫描仪将不会启动,应用程序也不会部署。
那么,我做错了什么??
