[jira] [Updated] (GROOVY-10076) No warning for type parameter that hides a type

["Eric Milles (Jira)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/GROOVY-10076?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Eric Milles updated GROOVY-10076:
---------------------------------
    Description: 
Consider the following:
{code:groovy}
class Type<T> {
  def <T> m(T t) {
  }
}
{code}

In this case, I think it was an accident to add "<T>" to the method declaration.

The method type parameter "T" hides the enclosing class type parameter "T" without warning.  I think you could get the same situation with "class T" in the same package.  ecj states "The type parameter T is hiding the type T".
