环境：19.3.0.0 centos7 pdb

问题：

java写了个jar，单独执行 util_GM.jar 没报错。通过loadjava将外部的bcprov-jdk15to18-1.77加载到数据库中，然后给工具类util_GM.jar也加载数据库中。

然后编写函数调用util_GM.jar包中的GM_encrypt方法，报错如下：

处理过程：cp $ORACLE_HOME/javavm/lib/security/java.security to

$ORACLE_HOME/javavm/lib/security/java.security.alt

文件新增 

security.provider.10=org.bouncycastle.jce.provider.BouncyCastleProvider

2) loadjava $ORACLE_HOME/javavm/lib/security/java.security.alt into CDB$ROOT using loadjava:

NOTE: THE RESOURCE CREATED MUST BE lib/security/java.security.alt

cd $ORACLE_HOME/javavm/lib/security/

loadjava -u sys/<syspasswd> -g public -v lib/security/java.security.alt

3) activate lib/security/java.security.alt

log into CDB$ROOT as SYS:

alter session set "_oracle_script"=true;

call javavm_sys.rehotload();

log into PDBS as SYS

alter session set "_oracle_script"=true;

create or replace java system;

还是图上错误。
