Steps to reproduce:

1. Create an Xtend2 file and open it in the editor.

2. Create contents that raises an error:
----
class Foo {
  test_fail() {
    newArrayList("ab", "abc").fold(0, [s,  max | Math::max(s.length, max)])
  }
}
-----

3. display the error message by moving the cursor over the error annotation on the left-hand side of the editor. 

4. press F2 to turn the tooltip into an actual window. 

-> the error message changes, it seems like the type parameters in the message are not displayed anymore. 

I.e., the message changes from:
---
Incompatible types. Expected org.eclipse.xtext.xbase.lib.Functions$Function2<java.lang.String,java.lang.Integer,? extends java.lang.Integer> but was org.eclipse.xtext.xbase.lib.Functions$Function2<java.lang.String,? extends java.lang.Object & super int,java.lang.Integer>
---

to

---
Incompatible types. Expected org.eclipse.xtext.xbase.lib.Functions$Function2 but was 
 org.eclipse.xtext.xbase.lib.Functions$Function2
---

this is kinda annoying when you want to copy'n'paste an error message ;)

This error does no appear with the tooltip over the underlined text.
