There are some artifacts in shrinkwrap which does not require JDK 1.7 to build, like:

• api
• bom
• build-resources
• dep-chain
• dist
• impl-base
• spi

  Only artifacts:

• api-nio2
• depchain-java7
• impl-nio2

   requries JDK 1.7 to build

But currently, it can be built only in JDK 1.7 environment, even for the artifacts which can be built in JDK 1.6, I think it would be better to make a profile to distinguish the artifacts built in JDK1.6+ and JDK1.7+, so that those artifacts which can be built in JDK1.6 will still build successfully in JDK 1.7 environment?

like:

  <profiles>
    <profile>
      <id>jdk7</id>
      <activation>
        <jdk>1.7</jdk>
      </activation>
      <modules>
        <module>api-nio2</module>
        <module>depchain-java7</module>
        <module>impl-nio2</module>
      </modules>
    </profile>
  </profiles>
