### Bug
- Which version of SkyWalking, OS and JRE?
the skywalking version is 7.0.0, use Centos7, java8.
- Which company or project?
the project is a weChat callback service.
- What happen?
I introduced oracle-10.x-plugin into the service agent. Recently, I found some NullPointerException error in the skywalking agent log. By looking up the source code of oracle-10.x-plugin, I think it may be caused by the cacheobject in line 70 of [PreparedStatementExecuteMethodsInterceptor.java](https://github.com/SkyAPM/java-plugin-extensions/blob/master/oracle-10.x-plugin/src/main/java/io/skywalking/apm/plugin/jdbc/oracle/PreparedStatementExecuteMethodsInterceptor.java) does not make a non null judgment.
This is error log.
