----------------------------------------------

             Summary: Unexpected type mismatch when having bounded type 
parameters
                 Key: GROOVY-10999

This might be related to GROOVY-10629.

I have the following program:

{code}
class Main {
  static final <U extends Number, H extends U> void test() {
    def x = java.util.Collections.<H, H>emptyNavigableMap().ceilingKey((H) 
null);
  }
}
{code}

h3. Actual behavior

{code}
org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:
Main.groovy: 3: [Static type checking] - Cannot call 
java.util.NavigableMap#ceilingKey(H) with arguments [H]
 @ line 3, column 13.
       def x = java.util.Collections.<H, H>emptyNavigableMap().ceilingKey((H) 
null);
               ^

1 error
{code}

h3. Expected behavior

Compile successfully

Tested against master (commit: 72cae725137e3a610b94e6927b18587c439f6f9b)
