tomcat-解决org.bouncycastle.asn1.ASN1Boolean非法循。。。

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

1. 进⼊tomcat WEB-INF下的LIB路径中。

2. 在该路径下执⾏ find . -name * -exec grep -l \"ASN1Boolean\" {} ;3. 发现查询出来的jar包有./fr-third-8.0.jar , ./bcprov-jdk-1.46.jar

4. 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5. 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。
