我要走了 sun.security.validator.ValidatorException: PKIX path validation failed: java.security.cert.CertPathValidatorException: Algorithm constraints check failed: SHA1withRSAsame 错误，当我从flume调用twitter源时。当我在google上搜索时，我才知道我的jdk可能是旧版本，但我的jdk版本是1.8.0\u45。因为我有最新的jdk，会有什么问题？使用命令 keytool -list -keystore /usr/jdk64/java-1.8.0-openjdk-1.8.0.45-28.b13.el6_6.x86_64/jre/lib/security/cacerts 我得到了以下结果
