我正在使用带有 1.0.0 版的 maven mstor 库的基本 mstor 逻辑，但它在 inbox.close() 方法上抛出了一个异常。注意：我没有对磁盘进行任何写入，所以这个异常很奇怪。作为一种尝试，我做了我的类，它调用这个代码来“实现可序列化”，但这并没有帮助。

此代码从 SpringBoot REST 服务运行。

如果我不执行 inbox.close()，则在以下方法完成后，在 Windows 上 mbox 文件仍处于打开状态（未由该库发布）。

这是基本代码：

Properties properties = new Properties();
properties.setProperty("mail.store.protocol", "mstor");
properties.setProperty("mstor.mbox.metadataStrategy", "none");
properties.setProperty("mstor.mbox.cacheBuffers", "disabled");
properties.setProperty("mstor.mbox.bufferStrategy", "mapped");
properties.setProperty("mstor.metadata", "disabled");
properties.setProperty("mstor.mozillaCompatibility", "enabled");
Session session = Session.getInstance(properties);

try {
store = session.getStore(new URLName("mstor:" + pathToMboxFile));

store.connect();
inbox = (MStorFolder) store.getDefaultFolder();

inbox.open(Folder.READ_ONLY);

Message[] messages = inbox.getMessages();

int bodyPartCount = 0;

// ***********************
// process all mbox data.
// *************************

for (int pos = 0; pos < messages.length; pos++)
{

// processing.
}

catch (NoSuchProviderException e)
{
log.debug("MboxController NoSuchProviderException Exception: " + e.getMessage());
}
catch (javax.mail.MessagingException e)
{
errors.append(e);
log.debug("MboxController MessagingException Exception: " + e.getMessage());
}
finally
{
// close the mbox store
try
{
inbox.close(false);
store.close();
}
catch (MessagingException e)
{
log.debug("MboxController Closing Store Exception: " + e.getMessage());
}
}

现在，虽然代码可以正常工作并返回 mbox 文本并关闭文件，但当 inbox.close(false) 运行时，我每次都会在 Tomcat 日志中得到这个错误堆栈（或接近它的东西）：
