buildbreak: package com.ibm.oti.shared does not exist

[sxa]

Something that went in yesterday has destabilised the builds seemingly across all platforms. Seen at adoptopenjdk CI but also visible in the OpenJ9 CI

Trying to figure out what caused this.

I believe this is fixed by #3207

Although the builds were broken (failed to run java -version), I don't believe the symptom described here was related.
