building master creates changes on file

[sebastienblanc]

Describe the bug
After Quarkus has been locally build with mvn clean install -DskipTests=true and I check git status I can see changes on files I haven'ts touched :

modified:   extensions/smallrye-context-propagation/deployment/src/test/java/io/quarkus/context/test/TransactionalBean.java
modified:   extensions/smallrye-context-propagation/runtime/src/main/java/io/quarkus/smallrye/context/runtime/SmallRyeContextPropagationTemplate.java
modified:   integration-tests/main/src/test/java/io/quarkus/it/main/ContextPropagationTestCase.java

Expected behavior
After a build i would expect only changes on the files I changed myself

To Reproduce
Steps to reproduce the behavior:

1. mvn clean install -DskipTests=true
2. git status
