JDK Requirement for Using the Java-Based Collection Plug-in
To use a Java-based collection plug-in with Oracle Database Security Central, you must have the JDK to compile and test your code.
Because the collection plug-in runs under the same JVM after it is shipped, Oracle recommends that you use the same JDK as the JDK that you use to start the agent. Compile your classes with the JDK by setting the -target option of the javac compiler to the same JDK version. Refer to the JDK documentation for details.
