Я использую SAPJco3.jar для подключения к SAP с использованием Java.Однако, когда я пытаюсь остановить свой мост, я получаю сообщение об ошибке.
Код отключения:
public void tearDown() {
log.info("tearDown() | Starting tear down ...");
log.info("tearDown() | Stopping {} JCO servers ...", jcoServerList.size());
System.out.printf("\ntearDown()| Stopping %s JCO servers ...", jcoServerList.size());
System.out.println();
for (JCoServer jcoServer : jcoServerList.values()) {
try {
jcoServer.stop();
jcoServer.release();
} catch (Exception e) {
log.error("Failed to STOP JCO server {} e={}", jcoServer.getProgramID(), e.toString());
}
}
jcoServerDataManager.clearAllData();
jcoServerDataManager = null;
log.info("tearDown() | Done with tear down!");
}
Я получаю следующую ошибку:

Когда я пытаюсь остановить мост, уже существуют некоторые соединения для этого моста, и состояние jcoserver изменяется с ALIVE -> STOPPING, и оно никогда не переходит в STOPPED.Если к серверу не подключены никакие соединения, он без проблем переходит в состояние ОСТАНОВЛЕНО.
Может ли кто-нибудь указать направление для этой проблемы?Есть ли способ, как я могу принудительно остановить мост?
Спасибо!
