Package: maven
Version: 3.6.0-1
Severity: normal

   * What exactly did you do?

Running maven with Java 7
$ mvn -version
Apache Maven 3.6.0
Maven home: /usr/share/maven
Java version: 1.7.0_10, vendor: Oracle Corporation, runtime:
/home/martin/martin-no-backup/opt/jdk1.7.0_10/jre


   * What was the outcome of this action?

Crash (error below)

   * What outcome did you expect instead?

Maven works

   * What is the reason?

/usr/share/maven/lib/wagon-http-shaded.jar contains a few files compiled for
Java 8, for example

org/apache/maven/wagon/providers/http/httpclient/ExceptionLogger.class:
compiled Java class data, version 52.0 (Java 1.8)

(wagon-http-shaded.jar is the only jar with java8 classes, all the others 41
jars in /usr/share/maven/lib/ are OK)

Trace:
constituent[42]: file:/usr/share/maven/lib/maven-builder-support-3.x.jar
