Hi everyone,

I'm trying to report long-standing annoyances encountered when using
the ScalaIDE in the interest of improving it. Here's one that's
fairly easy to reproduce:

Say I have two classes defined in the same package and the same file:

File: SomeOtherClass.scala

package com.example.foo

class MyClass(some: Int, params: Int)

class SomeOtherClass {
  def blerg {
    val someClass = new MyClass(123, 456)

    println(someClass)
  }
}

Activating the rename-class refactoring via alt-shift-r on either the
MyClass constructor call or the MyClass defintion does the right
thing: references to MyClass are renamed everywhere in this file.

Say the affected classes are in the same package, but two different files:

File MyClass.scala:

package com.example.foo

class MyClass(some: Int, params: Int)

File SomeOtherClass.scala:

package com.example.foo

class SomeOtherClass {
  def blerg {
    val someClass = new MyClass(123, 456)

    println(someClass)
  }
}

Here, renaming from the MyClass definition works and correctly renames
the .scala file; renaming from the MyClass constructor call works but
DOESN'T rename the .scala file.

Now say the affected classes are in different packages and different
files:

File MyClass.scala:

package com.example.bar.baz

class MyClass(some: Int, params: Int)

File SomeOtherClass.scala:

package com.example.foo

import com.example.bar.baz.MyClass

class SomeOtherClass {
  def blerg {
    val someClass = new MyClass(123, 456)

    println(someClass)
  }
}

Here, renaming from the MyClass constructor call has no apparent
effect, but renaming from the MyClass definition DOES work, and DOES
rename the relevant .scala file.

I just tested these scenarios in a minimal Scala project created with
the latest ScalaIDE milestone, running in Eclipse Kepler SR1.
