是什么导致了java.lang.InternalError (它扩展了VirtualMachineError)
是什么导致了java.lang.InternalError (它扩展了VirtualMachineError)
提问于 2011-12-09 13:36:24
当我尝试进行SVN同步时，我得到了这个错误。我不知道为什么会发生，有什么想法吗？在重新启动eclipse之后，它工作得很好，但是我想知道是什么导致了它，以及如何可能找不到这个罐子。

深入到在这里找到的代码，我可以看到:在第753行调用sun.misc.URLClassPath.JarLoader.ensureOpen()会导致在755行中引发InternalError。
该方法如下所示：
private void ensureOpen() throws IOException {
if (jar == null) {
try {
java.security.AccessController.doPrivileged(new java.security.PrivilegedExceptionAction() {
public Object run() throws IOException {
....
}
});
} catch (java.security.PrivilegedActionException pae) {
throw (IOException) pae.getException(); // this exception is thrown
}
}
}这里，java.security.AccessController.doPrivileged(PrivilegedExceptionAction<T>)是一个本地方法。文档是这里。
可以从文档中了解到，error可能是为处理public Object run() throws IOException {时发生的异常抛出的。
