背景
记录遇到一次奇怪的错误，在发布war包到Tomcat的时候，出现了org.bouncycastle.asn1.ASN1Boolean非法循环依赖的错误。

现象
第一台机器很早之前部署的并且也部署成功，第二台机器通过scp命令将第一台机器的整个tomcat拷贝到第二台上并且启动运行，tomcat抛出这个异常。
解决方案
- 进入tomcat WEB-INF下的LIB路径中。
- 在该路径下执行 find . -name * -exec grep -l "ASN1Boolean" {} ;
- 发现查询出来的jar包有./fr-third-8.0.jar , ./bcprov-jdk-1.46.jar
- 在该项目中帆软报表已经没有使用了，不知道为何还会引入这个fr-third-8.0.jar这个包
- 排除该包fr-third-8.0.jar，并且重新启动，启动完成。
小结
对于为什么会出现循环依赖的这个问题，为什么会不确定性出现，按理说依赖冲突应该所有的机器都会出现这个错误，会什么会不定性出现？还在进一步调研中...有结论会在此博客更新。
