In an upcoming release, the bundled JVM for the crawler plug-in and customer connector features will be transitioned to IBM Semeru Runtimes, Version 21. If your crawler plug-in or custom connectors utilize any features that are incompatible between IBM SDK, Java Technology Edition, Version 8 and IBM Semeru Runtimes, Version 21, you need to revise your code to ensure compatibility with future releases, such as Discovery 5.2.x and later.
