NullPointerException on validation [message #45279]

With my grammar I am getting NullPointerExceptions in
DatatypeRuleToken.internalMerge(String int)where the text is null -
usually because the text has not been completed by the user.

My grammar is rather complicated but the following grammar reproduces the
problem;-

Model :
(imports+=Import)*
(elements+=Class)*;

Import :
'import' importURI=STRING;

Class :
'class' name=ID ('extends' references=[Class])? (abbrev=ABBREV)?;

SPECIAL_ID : ID | INT ;
ABBREV: '<'SPECIAL_ID'>';

The following model text reproduces the problem;-
class A extends B<

Is this a bug?

Thanks.
