Additional information from the submitter: I'm currently unable to make a reproducible test case because I'm on macOS / JDK17 and cannot reproduce the issue here in my environment. The error does suggest the issue originates from JDK internals though, though I don't know what the code for Linux / JDK11 would look like specifically there.
