Kylin V10SP1桌面版下GBase 8s java udr异常处理
同样的GBase 8s数据库版本，自定义的java udr在Kylin V10SP1 服务器版（aarch64架构）下创建、运行正常，而在Kylin V10SP1 桌面版（aarch64架构）下时创建正常但运行UDR异常，报错如下：

PARAM is not NULL从错误的描述上来看：java.lang.NoClassDefFoundError: Could not initialize class sun.security.ec.CurveDB，提示为无法初始化sun.security.ec.CurveDB，这个类在两个平台的相同目录中jre/lib/ext/sunec.jar中确认存在。
当前的操作系统信息为：

KYLIN_RELEASE_ID="2303"出现异常操作系统（桌面版）和正常的操作系统（服务器版）的主要差别是：
- 服务器版本主要是基于CentOS或者相似发行版。
- 而桌面版如上面的信息，是基于debian的发行版。
根据以往的经验：由于桌面版的内核要高于服务器版，对程序的要求要新一些，当前GBase 8s自带的jre版本为jre 1.8.0_60，略显偏低，于是更换jre的版本为openjdk 1.8.0_232，重试（需要重启数据库，重新加载jvp），重新创建、运行UDR正常。
