Make static caching hash maps multithreading safe #372

Closed stefanuhrig closed 2 years ago

stefanuhrig commented 2 years ago

Two static hash maps that are use for caching values were not multithreading safe.

We change their type from HashMap to ConcurrentHashMap to avoid synchronization issues.

Fixes #371

This change is Reviewable

Thanks for reporting these two issues! I'll provide fixes separately - closing your PR without merging. (Very helpful nevertheless.)
