这种情况并不总是发生，我们无法恢复局势的稳定。我们认为这是一个多线程错误，并添加同步，但它似乎不工作，我能做什么 下面是获取方法：Java 看到这个jvm崩溃，我使用NIO读写文件，它发生在读的过程中，但并不总是什么'；这是不对的,java,jvm,nio,jvm-crash,Java,Jvm,Nio,Jvm Crash,这种情况并不总是发生，我们无法恢复局势的稳定。我们认为这是一个多线程错误，并添加同步，但它似乎不工作，我能做什么 下面是获取方法： public synchronized T get(long pos){ initBuffer(pos); return getValue((int) (pos & getPageModeValue())); } initBuffer用于初始化缓冲区文件并创建读取缓冲区，如果缓冲区是正确的缓冲区，则getValue只需使用缓冲区从文件中直接
public synchronized T get(long pos){
initBuffer(pos);
return getValue((int) (pos & getPageModeValue()));

还有类似的问题。可能是NIO写入问题，一些字节根本没有写入磁盘。但有时它写得正确，有时它不起作用。NIO写问题不是NIO读问题，两者都不应该导致JVM崩溃。当我读第11篇文章并使用READONLY
buffer=fc.map（FileChannel.MapMode.read_ONLY，start，niostant.PAGE_SIZE）时，文件长度是10它导致crash@user2806176“它”是什么？关闭UAC？重新安装？升级？
