[BUG] Inline bytecode transformer randomly deadlocking on Java 19 #2767
Description
When running tests, I appear to be hitting a deadlock in random places. This is occurring on tests not even using Mockito, so I assume this is down to the bytecode transformer. It appears to be totally random as to where it actually occurs, and sometimes it won't occur at all.

<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>3.0.0-M7</version>
</plugin>I can reproduce this on Mockito 4.8.0 as well.
