Description

Starting from Groovy 1.6 final I experienced a regression on the Collection.sort

{Closure}

method.
The minimal example to replicate it requires the following steps
1. Run groovysh
2. Write the following line
for (x in [1,2,3].sort

{it*2}

)

{ println x }
3. An exception is raised
ERROR java.lang.NoSuchFieldError: $const$1
at groovysh_evaluate$_run_closure1.doCall (groovysh_evaluate:2)
at groovysh_evaluate.run (groovysh_evaluate:2)
...

The same example with Groovy 1.5.7 worked fine, printing
1
2
3

On Groovy 1.6 the error can be replicated also with
for (x in [1,2,3].sort{0}) { println x }

The problem seems somehow related to the for cycle, because the following code doesn't throw exceptions
[1,2,3].sort

{it * 2}

[1,2,3].sort

{0}
