Are you using one of the recommended java jdks? https://docs.mendix.com/refguide/system-requirements#7-3-java
Apparently not all java distributions cover all timezone data, so i read on stackoverflow.
If that is not the issue, you may want to check if one of your userlib jars contains a specific version on the TimeZone class.
Or create a Mendix support ticket, it should not work like this of course.
I hope this helps.
