我知道“阻止访问”应该是什么意思：你正在使用内部库，不在公共API中的东西，而你根本就不应该使用它。
现在，据我所知，包“org.eclipse.osgi.util”中的类EclipseStarter是公共API的一部分。我引用：
This package specifies API to start the platform.
Clients may use the EclipseStarter loader class to start the platform.
The EclipseStarter class is the only defined API in this package.
EclipseStarter类的详细信息页面指出：
Special startup class for the Eclipse Platform. This class cannot be instantiated;
all functionality is provided by static methods.
Note that the fields on this class are not API.
我读过：方法可以使用吗？
我的代码：
import org.eclipse.core.runtime.adaptor.EclipseStarter;
这个已经发出警告“不鼓励访问：由于对所需库的限制而无法访问类型EclipseStarter [path-to-eclipse] \ plugins \ org.eclipse.osgi_3.7.2.v20120110-1415.jar”< / p>
我使用该类的代码：
try {
EclipseStarter.shutdown();
EclipseStarter.startup(null, null);
} catch (Exception e) {
e.printStackTrace();
}

答案 0 :(得分：5)
PlatformUI.getWorkbench().restart();是重启的正确方法（除非您运行的是纯'e4'RCP）。您需要查看导致事件循环错误的原因。
包含EclipseStarter的包在org.eclipse.osgi MANIFEST.MF中标有x-friends="org.eclipse.core.runtime"，这意味着它仅供org.eclipse.core.runtime和所有其他插件使用将得到气馁的访问警告。
