解决办法如下：
删除编译服务器/etc/java-8-openjdk/security/java.security 文件里jdk.tls.disabledAlgorithms 的 TLSv1, TLSv1.1 606 jdk.certpath.disabledAlgorithms=MD2, MD5, SHA1 jdkCA & usage TLSServer, \ 607 RSA keySize < 1024, DSA keySize < 1024, EC keySize < 224, \ 608 include jdk.disabled.namedCurves
重新启动Jack-server，问题解决：
./prebuilts/sdk/tools/jack-admin kill-server ./prebuilts/sdk/tools/jack-admin start-server
