Memory leak in PROVIDERS_MAP

Question

lukelast opened this issue a year ago · comments

Describe the bug
Each instance of Faker() created will permanently consume memory. If you create enough instances you'll OOM.

To Reproduce
Code to reproduce is here:
https://github.com/lukelast/datafaker-bug-repro/blob/main/src/main/kotlin/Main.kt

The summary of the code is to create a lot of instances, let them be GC'd, then check heap usage.

Expected behavior
I expect heap usage to go back to the original size as everything is GC'd away.

Versions:
