Description Robert von Massow

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

for a cast expression like :

null as Iterable

the compilation is silently broken.
Xbase should fill up missing type arguments with wildcards.

Preliminary scheduled for 2.0RC1

Comment 3 Sven Efftinge

Pushed to master.

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.
