Caused by: sun.security.validat
or.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

问题由来：
aliyun kafka 使用ssl从公网连接，之前使用的证书好好的，过了一段时间发现不太行了

解决思路：
证书问题，更换官方推荐的证书，即修复了问题
旧的证书：kafka.client.truststore.jks
新的证书：only.4096.client.truststore.jks
