Tamas Cservenak updated MNG-8178:
---------------------------------
Component/s: Core
> Profile activation based on OS properties is broken for "mvn site"
> ------------------------------------------------------------------
>
> Key: MNG-8178
> URL: https://issues.apache.org/jira/browse/MNG-8178
> Project: Maven
> Issue Type: Bug
> Components: Core
> Affects Versions: 3.9.7, 3.9.8
> Reporter: Christian Kohlschütter
> Assignee: Guillaume Nodet
> Priority: Blocker
> Fix For: 4.0.0, 3.9.9, 4.0.0-beta-4
>
>
> MNG-5726 introduced a breaking change that makes "mvn site" fail when
> profiles based on OS activation are used.
> From commit f860a8693d38292c8ce9ee3b6a883559e7a94796
> maven-model-builder/src/main/java/org/apache/mavqen/model/profile/activation/OperatingSystemProfileActivator.java:
>
> {code:java}
> String actualOsName =
> context.getSystemProperties().get("os.name").toLowerCase(Locale.ENGLISH);
> String actualOsArch =
> context.getSystemProperties().get("os.arch").toLowerCase(Locale.ENGLISH);
> String actualOsVersion =
> context.getSystemProperties().get("os.version").toLowerCase(Locale.ENGLISH);{code}
> context.getSystemProperties() may be empty (or not contain any of these three
> keys), which makes toLowerCase(Locale) fail with a NullPointerException.
> Steps to reproduce:
>
> {code:java}
> git clone https://github.com/kohlschutter/junixsocket.git
> git checkout 65602a9054eb232635678e1aa2f682969aaa059f
