Can I use Java 7 with Vert.x any version ? : I need to use Vert.x as per requirement. Need to implement vert.x + java 7 . Is it 

Just want to know , Can I Implement Vert.X with Java 1.7, as Vert.X have lambda expression (i.e. not supported by Java 7) , So Is it compulsory Vert.X + Java 8 or Vert.X provided some alternative of Lambda Expression or lower version of Vert.X is Compatible with Java 7.

Thanks in advance.
