无法在VisualVM中打开某些应用程序 [英] Cannot open some applications in VisualVM

问题描述

我正在使用Ubuntu 14.04和Oracle JDK 8.我想使用VisualVM检查我的应用程序的性能。我可以检查其他应用程序，如JDownloader，但我无法检查自己的应用程序和Eclipse 4.3。在我重新安装Ubuntu之前，我使用的是JDK 7，我没有任何问题，并且在没有任何配置的情况下使用它。它给出了以下日志。

I am using Ubuntu 14.04 with Oracle JDK 8. I want to inspect performance of my application using VisualVM. I can inspect other applications like JDownloader but I can't inspect my own applications and Eclipse 4.3. Before I made fresh install of Ubuntu, I was using JDK 7 and I have no problem and using it without any configuration. It gives following log.

推荐答案

使用jvm参数运行eclipse和你的应用程序-Duser.language = en -Duser。 country = us ...

那么你就可以了le with jvisualvm。


for eclise将这两行放在eclipse.ini中

run eclipse and your application with jvm parameters -Duser.language=en -Duser.country=us ...
then you will be able profile with jvisualvm.

for eclise put this two lines in eclipse.ini

-Duser.language=en
-Duser.country=us

也许你预先安装的Ubuntu有语言设置为英语，你没事。

maybe your pre installed Ubuntu had languge settings as english and you was ok.
