Paul King updated GROOVY-9660:
------------------------------
Description:
*code example :*
{code}
trait Data {}
class TestData implements Data {}
class AbstractData<D extends Data>{ D data }
def test = new AbstractData<TestData>()
{code}
*when i compile groovy，it compile failed:*
{noformat}
1 compilation error:
The type TestData is not a valid substitute for the bounded parameter <D
extends Data>
at line: 7, column: 29
{noformat}
Is this the wrong way to write it？
