Subject: Welcome, Maurizio Cimadamore
Message-ID: <B4A4A7C8-F436-4AD5-9359-A9C1A51E99C1@Sun.COM>

Compiler folk,

I am delighted to announce that Maurizio Cimadamore has recently  
joined Sun's Language Tools team and will be working on javac. He will  
also be a member of the OpenJDK Compiler Group, so you can expect to  
see and hear more from him here :-)

He comes to us from the University of Bologna, Italy, where he worked  
on the studying language design issues, and reification of generic  
types. To this end, he developed a prototype compiler called EGO  
(based on the research work of Mirko Viroli, his PhD tutor); this  
compiler is an extension of javac allowing generic types to be better  
supported at runtime so that type-dependent operations (such as cast  
and instanceof) can be applied to generic types too without any risk  
of heap pollution. Starting from this work he then developed a  
prototype of a JVM with runtime support for generic types exploiting  
the same reification scheme exploited within the EGO compiler.

Welcome Maurizio!  It's great to have you on board!  And I'm sure the 
Dublin guys will take good care of you until we can get you over here w/ 
the rest of the compiler team in the Bay Area.
Regards,
Janet

It looks like we've switched now away from the internal aliases.

Here's a code review I recently sent internally, which really should  
have been external.

Vladimir, Tom, Steve:  Thanks for the reviews; I'll put you in the  
changeset comment as soon as I learn your OpenJDK names.

Non-Sun people:  Welcome to the party!

IncompatibleClassChangeError

P.S.  This is my first stumble toward a mercurial-based putback....

To get a more "open" feel for this review, I put this webrev up on an  
external site.
The repo. is on my MacBook.  I think only the Bugster interactions  
have required SWAN access.

However, I'm sending the request to our internal mail alias, not the  
openjdk group alias.
Also, this putback can't go anywhere yet, since the parent repo.  
(hotspot-comp) is still the experimental one.
(My repo. is freshly cloned from http://hg.openjdk.java.net/jdk7/jdk7/ 
hotspot .)

I generated the webrev using this command:
   /java/devtools/share/bin/webrev  -ON -i 6610906-comments.html

The contents of the "author comments" file looks like this:

For putback to <a href="http://hg.openjdk.java.net/jdk7/hotspot-comp- 
gate/hotspot">http://hg.openjdk.java.net/jdk7/hotspot-comp-gate/ 
hotspot</a>
<br><a href="http://bugs.sun.com/bugdatabase/view_bug.do? 
bug_id=6610906">6610906</a>: inexplicable IncompatibleClassChangeError
<br>Summary: dependency check must treat polymorphic interfaces  
consistently
<br>Reviewed-by: ??

I'll strip the formatting (which webrev should have put in for me)  
and use it as a changeset comment.

D'oh.  Sorry folks for the newbie noise.  We're switching to  
*hotspot*-compiler-dev at ojdk.  -- John
