我正在将基本的mstor逻辑与maven mstor库的1.0.0版一起使用，但是它在inbox.close（）方法上引发了Exception。注意：我没有对磁盘做任何写操作，因此此异常很奇怪。我尝试将此类代码称为“实现序列化的实现”，但这没有帮助。
此代码从SpringBoot REST服务运行。
如果我不执行inbox.close（），则在Windows中，以下方法完成后，mbox文件仍处于打开状态（此库未释放）。
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，尽管代码确实起作用并返回mbox文本并关闭文件，但是当inbox.close（false）运行时，每次在Tomcat日志中我都会得到此错误堆栈（或接近它的东西）： / p>
