Description

We have a class extending java.math.BigDecimal, also a method having a BigDecimal argument
The method works fine if we call it with a BigDecimal object. If the method is called with an instance of the extending class, a MissingMethodException is thrown.

groovy.lang.MissingMethodException: No signature of method: ConsoleScript16.f() is applicable for argument types: (ExtendedBigDecimal) values: [1]
Possible solutions: f(java.math.BigDecimal), is(java.lang.Object), run(), run(), any(), any(groovy.lang.Closure)
