Comment 1 Philipe Mulet CLA 2004-06-25 10:55:37 EDT 
Reproduced in latest.
Comment 2 Philipe Mulet CLA 2004-06-25 12:07:31 EDT 
Compiler was misgenerating signatures for generic interfaces. Therefore, it 
was failing to read it back in on incremental compilation scenario.
Comment 3 Philipe Mulet CLA 2004-06-25 12:07:54 EDT 
Fixed. Added regression test: GenericTypeTest#test211
Comment 4 Philipe Mulet CLA 2004-06-25 12:13:49 EDT 
Also added: GenericTypeSignatureTests#test015
