@umjsio I suspect that this issue is already fixed in main (the Jython version used in versions prior to WLS 14.1.1 has a bug that I have worked around) but I will add some more safeguards to make sure. The plan is to release WDT 4.0.1 later this week after incorporating the April 2024 PSU changes to the aliases.

@umjsio if you want to try out the fix, you can build your own installer from the main branch. It requires JDK 17 and a recent version of Maven. You can skip the unit tests using mvn clean install -DskipTests. After running the build, the installer will be found in the installer/target/ directory.
