    Description

      The invalid result appears only in 2.0.0 version of Groovy:

      dm@dmc:~/bin/groovy-2.0.0/bin> ./groovysh
      Groovy Shell (2.0.0, JVM: 1.6.0_29)
      Type 'help' or '\h' for help.
      ---------------------------------------------
      groovy:000> def c =

      {def s; if (it.y == null) s = true; else s = it.z < it.x - 1 ? null : true; s}

      ; c(z: 0, y: 2, x: 3)
      ===> false
      groovy:000>

      In Groovy 1.8.6 the result is correct.

      dm@dmc:~/bin/groovy-1.8.6/bin> ./groovysh
      Groovy Shell (1.8.6, JVM: 1.6.0_29)
      Type 'help' or '\h' for help.
      ----------------------------------------------
      groovy:000> def c =

      {def s; if (it.y == null) s = true; else s = it.z < it.x - 1 ? null : true; s}

      ; c(z: 0, y: 2, x: 3)
      ===> null
      groovy:000>

      It can be fixed by replacing the ternary operator with 'else if' and 'else'.
