"mvn site" fails on dependency management information when using EAP 6 BOMs

Issue

• Running 'mvn site' under java 1.7 fails in DependencyManagement section due to a reference to tools.jar hard-wired to java 1.6. Due to this problem, our CI server claims the build has failed. However, its only the DependencyManagement analysis that is failing, wrongly, a false negative. My only workaround now is to disable DependencyManagement analysis.

[INFO] Generating "Dependency Management" report    --- maven-project-info-reports-plugin:2.8
[WARNING] Unable to create Maven project for com.sun:tools:pom:1.6 from repository.
org.apache.maven.project.ProjectBuildingException: Error resolving project artifact: Failure to find com.sun:tools:pom:1.6 in https://*******.

This are the artifact that reference tools.jar:

 <groupId>org.jboss</groupId>
  <version>11-redhat-1</version>
  <artifactId>jboss-parent</artifactId>

This is the segment in that file. The above failure does not occur when I comment these lines out.

  <dependencyManagement>
    <dependencies>
      <dependency>
        <groupId>com.sun</groupId>
        <artifactId>tools</artifactId>
        <scope>system</scope>
        <version>1.6</version>
        <systemPath>${com.sun.tools.path}</systemPath>
      </dependency>
    </dependencies>
  </dependencyManagement>

Changing JAVA_HOME to the 1.7 JRE or JDK does not resolve.
Neither does: mvn site -Djava-home=/path to java 1.7
