Eric Milles updated GROOVY-11830:
---------------------------------
Description:
Consider the following:
{code:groovy}
trait A {
abstract def m()
}
class B {
protected def m() { 'b' }
}
class C extends B implements A {
}
print new C().m() // IllegalAccessError
{code}
The trait {{A}} could also be an interface. It specs out a public method.
When a super class provides a protected or package-private method (when in same
package as extending class), there is no compiler error/warning or public
bridge method created to prevent an {{IllegalAccessError}} at runtime.
If the super class method is private, there is no compiler error and the result
is an {{AbstractMethodError}} at runtime.
