------------------------------------

             Summary: IllegalArgumentException: null argument for primitive 
lacks context
                 Key: GROOVY-11203
                 URL: https://issues.apache.org/jira/browse/GROOVY-11203
             Project: Groovy
          Issue Type: Improvement
          Components: groovy-runtime
            Reporter: Eric Milles
            Assignee: Eric Milles


Consider the following:
{code:groovy}
void setX(int x) {
  print x
}
def map = [:]
x = map.x // ParameterTypes#coerceArgumentsToClasses does not deal with null 
and primitive
{code}

Call to {{setX(int)}} via property write throws {{IllegalArgumentException}} at 
runtime.  The exception message and stack-trace don't provide much context.

{code}
java.lang.IllegalArgumentException
