Description David Audel CLA 2006-09-25 09:29:28 EDT 
The compiler doesn't report an error for an unresolved type argument if the parameterized type is unresolved.

e.g.
package p;
public class X {
  List<Zork> l;
}

There is only one error message:
  'List cannot be resolved to a type'

It would be interesting to have another error message to signal that 'Zork' is unresolved.
Comment 1 Philipe Mulet CLA 2006-09-26 10:50:01 EDT 
Qualified param type refs are also missing support.
e.g.

public class X {
  Map<Zork,Zork>.Entry<List<Zork>,List<Zork>>	entry;
}
Comment 2 Philipe Mulet CLA 2006-09-26 12:22:10 EDT 
Added support for being resilient for both single and qualified param references.
Note that it will never go beyond the next set of arguments for qualified refs.

e.g. Zork2 and Zork3 are not going to be complained until Map got resolved properly; but Zork will be reported as missing now.

Map<Zork,Zork>.Entry<List<Zork2>,List<Zork3>>

Additionnal patch

Incremental improvement to remove limitation for qualified refs where only next arguments were resolved. Now they will all be attempted to be resolved.
