> Key: SUREFIRE-1818
> URL: https://issues.apache.org/jira/browse/SUREFIRE-1818
> Project: Maven Surefire
> Issue Type: Bug
> Affects Versions: 2.22.1
> Reporter: Anton Ermolenko
> Priority: Major
> Attachments: image-2020-07-11-18-57-41-164.png
>
>
> For unknown reason when running tests Surefire version 2.22.1 buffers logging
> messages in memory in {{ConcurrentLinkedQueue}} which leads to
> OutOfMemoryError when amount of logging messages is sufficiently large. If
> amount of memory is big enough to hold those messages, Surefire will print
> those log messages after running the tests.
> Downgrading to 2.18.1 resolves the issue and log messages appear on the
> terminal without delay.
> While it's printing those messages the following stack trace can be observed:
> {code:java}
