背景
記錄遇到一次奇怪的錯誤，在發布war包到Tomcat的時候，出現了org.bouncycastle.asn1.ASN1Boolean非法循環依賴的錯誤。

現象
第一台機器很早之前部署的並且也部署成功，第二台機器通過scp命令將第一台機器的整個tomcat拷貝到第二台上並且啟動運行，tomcat拋出這個異常。
解決方案
- 進入tomcat WEB-INF下的LIB路徑中。
- 在該路徑下執行 find . -name * -exec grep -l "ASN1Boolean" {} ;
- 發現查詢出來的jar包有./fr-third-8.0.jar , ./bcprov-jdk-1.46.jar
- 在該項目中帆軟報表已經沒有使用了，不知道為何還會引入這個fr-third-8.0.jar這個包
- 排除該包fr-third-8.0.jar，並且重新啟動，啟動完成。
小結
對於為什么會出現循環依賴的這個問題，為什么會不確定性出現，按理說依賴沖突應該所有的機器都會出現這個錯誤，會什么會不定性出現？還在進一步調研中...有結論會在此博客更新。
