几天前,我们决定开始在我们的 Eclipse RCP 应用程序中使用 Guava。我从http://central.maven.org/maven2/com/google/guava/guava/14.0.1/下载了 guava-14.0.1.jar 。
在我启动 eclipse.exe 后,应用程序崩溃了。.metadata/.log 文件包含以下错误:

如果应用程序以管理员身份运行,则不会出现错误。
该应用程序是 64 位的,因此这不是 UAC 虚拟化问题。但看起来问题与权限有关。
guava-14.0.1.jar 似乎是一个有效的 OSGi 包:https ://code.google.com/p/guava-libraries/issues/detail?id=688 (至少我在 MANIFEST.MF 中找到了所有必要的标头)
有什么建议么?
