      I am running APEX 20.1 with ORDS 19.4.6 on Tomcat 9 on Linux with JDK 1.8. I can see memory leak message in tomcat catalina.out file.

       

      2020-06-08T09:48:19.988Z WARNING The web application [apex] registered the JDBC driver [oracle.jdbc.OracleDriver] but failed to unregister it when the web application was stopped. To prevent a memory leak, the JDBC Driver has been forcibly unregistered.
      2020-06-08T09:48:19.991Z WARNING The web application [apex] appears to have started a thread named [Timer-0] but has failed to stop it. This is very likely to create a memory leak. Stack trace of thread:
