Description Robert von Massow CLA 2011-04-08 08:23:44 EDT 
Build Identifier: 2.0.0.v201104080435

There is currently no suitable validation for missing type parameters. The validation should be the same as for the parameter ?. 

Reproducible: Always
Comment 1 Sven Efftinge CLA 2011-04-08 08:29:41 EDT 
for a cast expression like :

null as Iterable

the compilation is silently broken.
Xbase should fill up missing type arguments with wildcards.
Comment 2 Sebastian Zarnekow CLA 2011-05-04 06:11:38 EDT 
Preliminary scheduled for 2.0RC1
Comment 3 Sven Efftinge CLA 2011-05-04 09:59:08 EDT 
postponed to SR1

The following test compiles and executes without errors:

def void castNull() {
  var raw = null as Iterable
  var strings = null as Iterable<String>
  var Iterable assignStringsToRaw = null as Iterable<String>
  var Iterable<String> assignRawToStrings = null as Iterable
  var Iterable assignRawToRaw = null as Iterable
  var Iterable<String> assignStringsToStrings = null as Iterable<String>
  if (raw != strings)
    throw new IllegalStateException()
}

Please reopen if I missed the point of this issue.
