Seems to be fixed with ical4j 3.2.14.
@ArnyminerZ Can you please try your test (from the linked ical4j issue) with ical4j 3.2.13 and 3.2.14 and verify that it's fixed? And if yes, prepare a PR that updates to 3.2.14 and closes this issue.
ArnyminerZ commented
Looks like it has been fixed at some point. So patches needed. Both the ICS posted by Sunik and the one in the ical4j issue work fine.
ArnyminerZ commented
Closing until further cases

It's fixed without updating to 3.2.14?
Ah we're on 3.2.14 already
