Question

我试图在Windows 7 64位上使用jvisualvm配置一个简单的java应用程序。我正在使用Java 8和JDK 1.8.0_131。我能够看到我的应用程序并使用VisualVM的Sample选项卡，但是当我使用Profile选项卡的CPU选项时，我得到一个＆＃34; Redefinition失败，错误62＆＃34;。此错误在线记录，常见的解决方案是在启动应用程序时包含标志-Xverify：none。但是，使用此标志对我没有影响。我已经尝试了JVisualVM本身和我的简单程序jar都没有区别。以下是我正在使用的终端命令。

将Xverify与简单程序一起使用。

java -jar SimpleProfile.jar -Xverify:none

将Xverify与jvisualvm一起使用

./jvisualvm.exe -J-Xverify:none

两者都是从Git Bash终端运行而没有效果。我也在CMD中尝试过类似的命令。

我的PC上没有管理员权限，我注意到我无法使用Windows资源监视器。这可能与问题有关，还是我的论点有问题？

额外信息：当探查器失败时，我在终端

中收到以下错误

Answer 1

java -Xverify：none -jar SimpleProfile.jar有效。我想我没有用尽所有的选择。

JVisualVM -Xverify：none无法解决重定义失败，错误62
