我們在一個Servlet容器上使用Xodus，應用時不時拋出這個錯誤（不知道是什么原因）jetbrains.exodus.ExodusException: Can't acquire environment lock after 0 ms. Lock owner info: null    at jetbrains.exodus.log.Log.tryLock(Log.java:935)    at jetbrains.exodus.log.Log.<init>(Log.java:91)    at jetbrains.exodus.env.Environments.newLogInstance(Environments.java:137)    at jetbrains.exodus.env.Environments.newLogInstance(Environments.java:115)    at jetbrains.exodus.env.Environments.newLogInstance(Environments.java:104)    at jetbrains.exodus.env.Environments.newInstance(Environments.java:49)    at jetbrains.exodus.env.Environments.newInstance(Environments.java:39)什么可能導致這種情況發(fā)生？示例用法：public void put(String instance, final String storeName, final String key, final String value) {    final Environment env = Environments.newInstance(xodusRoot + instance);    env.executeInTransaction(new TransactionalExecutable() {        @Override        public void execute(@NotNull final Transaction txn) {            final Store store = env.openStore(storeName, StoreConfig.WITHOUT_DUPLICATES, txn);            store.put(txn, StringBinding.stringToEntry(key), StringBinding.stringToEntry(value));        }    });    env.close();}如果這put方法是從一個Servlet端點調用，服務器因此多個并發(fā)客戶端調用此方法。
