我正在尝试使用jdk6中打包的visualvm工具来配置本地JBoss 7服务器。我可以将visualvm连接到本地jboss服务器。但是，如果我在visualvm的profiler选项卡中启动CPU分析，JBoss服务器会转储大量错误消息，如下所示。
为什么？

在第%JBOSS_HOME%/bin/standalone.conf.bat行
":JAVA_OPTS_SET"添加以下行
set "JAVA_OPTS=%JAVA_OPTS% -Xshare:off -Djboss.modules.system.pkgs=org.netbeans.lib.profiler.server -Dorg.osgi.framework.bootdelegation=org.netbeans.lib.profiler.server,org.netbeans.lib.profiler.server.*"
或者以任何其他有效的方式添加提到的java选项。

我将该行放在standalone.bat中，如下所示：
set "JAVA_OPTS=%JAVA_OPTS% -Xshare:off -Djboss.modules.system.pkgs=org.netbeans.lib.profiler.server -Dorg.osgi.framework.bootdelegation=org.netbeans.lib.profiler.server,org.netbeans.lib.profiler.server.*"
