最近在用FISCO BCOS搭建私链来做项目，本地连我们自己搭建的测试环境FISCO BCOS时，报了些莫名其妙的错，连自己电脑搭建的一点也没问题，证书也都是按环境拷贝的；

关键错误信息如下：

Caused by: sun.security.validator.ValidatorException: PKIX path validation failed: java.security.cert.CertPathValidatorException: Algorithm constraints check failed on disabled algorithm: secp256k1

Caused by: javax.net.ssl.SSLHandshakeException: General OpenSslEngine problem

Error: try to connect nodes with both ecdsa and sm context failed

刚开始以为是jar包冲突导致的，换了几个关键包的版本，都没起作用

运行环境如下图

经过尝试，最终得到2个解决方法

1.用高版本jdk，我一直用的jdk8，换成jdk11后，启动成功，问题解决；

2.修改jdk8的java.security文件，注释掉jdk.disabled.namedCurves，文件目录为jdk1.8.0/jre/lib/security，启动成功，问题解决；
