This seems kind of bad.  Not even looked at for 3.1?

Comment 2 Jerome Lanneluc

2005-05-13 04:34:33 EDT

Sorry Steve, we somehow missed it. We'll provide a fix for RC1.

Comment 3 Jerome Lanneluc

Proposed patch

Changed BindingKeyParser.Scanner#nextToken() to not return a TYPE if the
character corresponds to a base type signature and the previous one is '.'.

Comment 4 Jerome Lanneluc

2005-05-13 04:45:22 EDT

Created attachment 21093 [details]
