--------------------------------
Summary: Maven install failure with multi-threads(-T option)
Key: MNG-7365

Project: Maven
Issue Type: Bug
Components: Command Line
Affects Versions: 3.8.1
Environment: 1. Operating System & Hardware
macOS Monterey 12.0.1
with 6-Core Intel Core i5
2. JDK version
openjdk version "1.8.0_292"
OpenJDK Runtime Environment (AdoptOpenJDK)(build 1.8.0_292-b10)
OpenJDK 64-Bit Server VM (AdoptOpenJDK)(build 25.292-b10, mixed mode)
Reporter: Jiseong Bak
Attachments: karaf_install_multi_thread.log,

I found that build failure occurs with multi-threads, using `-T` option. I'm
the researcher on automated software engineering and faced this problem while
running a script that installs vast amount of open-source projects using Maven.
This happens on one project, [karaf|https://github.com/apache/karaf]. If I find
other cases like this, I'll investigate and report them for discussion here.
Currently, I'm not sure why this corner case happens.
```bash
mvn clean install -DskipTests -V # success
mvn clean install -DskipTests -V -T 6 # failure
```
