--------------------------------

             Summary: Trailing space in profile '<id>' element causes Maven to blow up
                 Key: MNG-7692
                 URL: https://issues.apache.org/jira/browse/MNG-7692
             Project: Maven
          Issue Type: Bug
          Components: Profiles
    Affects Versions: 3.9.0, 3.8.7
         Environment: Windows 10 / Maven 3.9.0 / JDK 17
            Reporter: Jeff Thomas


If the profile id contains leading or trailing whitespace, the maven build blows up spectacularly with no indication of the real problem.

Removing the whitespace fixes the problem.

Normally leading/trailing whitespace in XML is ignored I believe? 

Marked as Prio 'Minor' because once you know what the problem is the fix is simple. :)
