我正在尝试运行 jbilling 4.4.1。但是我不断收到以下错误;
Exception in thread "ActiveMQ Scheduler" java.lang.IllegalStateException: Can't overwrite cause with java.lang.IllegalStateException: Illegal access: this web application instance has been stopped already. Could not load org.apache.activemq.broker.region.Queue$8. The eventual following stack trace is caused by an error thrown for debugging purposes as well as to attempt to terminate the thread which caused the illegal access, and has no functional impact.
