  tomcat          


      : Illegal access: this web application instance has been stopped already. Could not load java.lang.Object. 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.

 理由は、tomcatを再起動する時、前のtomcatのスレッドがまだ完全に閉じられていないため、新たにtomcatを起動するとこの異常が報告されますが、これは正常に使うことに影響しません。解決方法も簡単です。tomcatのserver.xmlのreloadable=「true」をfalseに変更すればいいです。
