Description

To reproduce:
Define an interface A in File A.groovy:

A.groovy:

interface A {
}

In groovyConsole add Folder containing A.groovy to class path and define an interface B:

interface B extends A {
}
println("Hello World");

Trying to run the script the first time results in the error message:
Exception thrown: loader (instance of groovy/lang/GroovyClassLoader$InnerLoader): attempted duplicate class definition for name: "A"
java.lang.LinkageError: loader (instance of groovy/lang/GroovyClassLoader$InnerLoader): attempted duplicate class definition for name: "A"

Second time execution gives no error. You have to clear the script context to reproduce the error. It is also necessary to have A in a separate file.
