Description

The issue seems to appear more often since upgrading to CheckStyle 9.X. However, the issue seems to rely in checkstyle mojo.

I initially reported the issue at: https://github.com/checkstyle/checkstyle/issues/10934

I consider checkstyle used in a maven multi-module project.

<!-- https://mvnrepository.com/artifact/org.apache.maven.plugins/maven-checkstyle-plugin -->
<maven-checkstyle-plugin.version>3.1.2</maven-checkstyle-plugin.version>
<!-- https://mvnrepository.com/artifact/com.puppycrawl.tools/checkstyle -->
<checkstyle.version>9.1</checkstyle.version>

I end with OutOfMemory issues in a compilation step going through all modules:

16:03:39,815 [INFO] — maven-compiler-plugin:3.8.1:compile (default-compile) @ dp-proxy —

I can not share the code as the project is private.
