• Type: Improvement

Description

Consider the following:

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

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