Any reason why Isis uses Maven enforcer [2.2.1,3.0.0)?

[Henry Saputra]

Hi All,

Any particular reason why Isis has Maven enforcer of

<requireMavenVersion>
  <version>[2.2.1,3.0.0)</version>

instead of just put lower limit like:

<requireMavenVersion>
  <version>[2.2.1,)</version>

Thanks,

Henry
